I've had a few people point out that my $1000/kg price for graphene is way overblown, since GMG (the very company I talk about in this video) have claimed to get the price down to $2 per kilogram. I kinda sorta just a little hinted at the fact that they are bringing the costs down, but I didn't put it into numbers. That is really something I should have explored more in the video and looking back it was a missed opportunity because that's an important and interesting development.
Another thing I like to know is how much graphene do they actually need for the battery? If it's holding charges so well, I imagine it would need much less graphene than lithium for the same amount of energy.
Don't forget, just like graphene Joe, you still have potential. It doesn't matter when you tap into that potential, just that you do. And I think this RU-vid channel is a great platform to get out science based material and delivers it in a way that is understandable. Thanks for sharing your potential!
@@Mr1121628 what? The future of our nation depends on people like the Joe's and Hank Greens of the world. RU-vid is a wonderful edutainment resource and those I want to do well, I want to provide support to them, even if it is hokey.
@@joshcampbell5159 People like you are important too, the ones who actually realize what an amazing gift the internet CAN be, Mr11 is probably only 11 years old, to him showing any sort of appreciation to fellow humans is considered "cringe" or whatever.
For that “Gifted kid” who’s now making content for RU-vid, sounds like the story for a ton of ADHDers. You have attained a level of success that is helping the world through informing and entertaining people, and I for one thank you for it.
no one cares about all these videos with magical battery solutions. stop making them for easy money. we want actual REAL batteries that can be held not BS
@@Blox117 He's literally just explaining a theory of how these batteries would work IF they were being implemented. If you actually watched the video, which you didn't, you would know he said MULTIPLE TIMES that use of these batteries in the future was unlikely. Also you're replying to someone's comment, not the video. Get off RU-vid gramps and spew your senile garbage somewhere else.
The $1,000 per kg is not accurate. GMG is producing graphene for less than the cost of graphite. Putting it closer to $2 per kg, not $1,000 per kg. They're most definitely real batteries and should be to market this year! $GMGMF $GMG.V
I work on the electrochemical properties of graphene. I've started to joke about graphene as follows: Graphene is the material that can do absolutely anything..... except leave the lab.
That's funny ! I ride bikes and we heard so much about the new kid on the block ( graphene) and how it was going to change the way bike frames were built , but we still waiting
@@jimbo4203 oh, you are absolutely right. And that is the exact issue. The bottleneck for graphene is not processing, or even raw materials. It is all about synthesis. I can confidently say that the person who finds a way to scale graphene production in a cost-effective manner will be a billionaire.
Here is a variation: Graphene is the material of the future ... and it always will be. (Hopefully that is not true, I'm really excited about the possibilities that Joe has shown us!)
I am personally excited to see graphene used in auto sport (I assume by that time sport might be the only permitted use of internal combustion engines) first for body panels, then eventually maybe for engine parts, imagine a connecting rod or piston that weighs a few grams or so is stronger than chrome moly alloys and has the heat properties of the graphite coating currently used in some of the best engines (bmw S54) only as a thin layer on piston faces
This reminds me of early Li-ion. Took 20 years before it filtered in the market when I discovered it working at a big alkaline battery manufacturer. At the time Li-ion was already 20-30 years into development. These things take time indeed.
@hen ko So true, but they are also correct. We have groundbreaking functional battery technologies in the pipe. Problem is if you invest 6 billion$ in a factory, what if someone the day after invents a 50 times better battery ? We need governments to pull together and make it happen. We have a serious problem to solve, and developers and investors are to small in the separated market today to lift the task at hand. Perhaps multiple governments creating an Umbrella organization to make it happen is the answer.
@@TrickOrRetreat Good point. Maybe if we still had a public space agency to research stuff like this then we wouldn't have gotten trapped in this lithium economy from hell.
@@TrickOrRetreat Governments don’t function nearly as well as you think. Get a bunch of governments together on a project like this and they will end up entrenching the wrong technology by putting too much money in that encouraging very sub-par development. Remember, we’re talking about technology that isn’t even ready yet. That’s a hard problem, and how do bureaucrats direct research they don’t even understand?
As a 40-something (equally questioning my remaining life's potential) I remember having a science poster of the Bucky ball in my bedroom in the nineties, and being quite excited about what it could mean for chemistry, computer science and all sorts of scifi. It's been slow going, apparently, both graphene and me...
{it been slow going, apparently, both graphene and me...}. But, you are making it. And that is all that really matters. Well, maybe not (ALL). I'm sure you would have like to complete this project many years past. So you can take the (next step). And you would have. Except for (politics). Any great paradigm changer like this, will cause all of the roadblocks the system has put in place (engineered to fail). This kind of tech will cause all of those (stops) to fall over. Of course politics will put the clamp on this awesome tech, for as long as possible. Turns out, (as long as possible), was this long. (Slow going), true. But it happened.
My first encounter with Bucky balls was a novel by no less luminary authors than Arthur C Clarke and hard-scifi maestro Stephen Baxter, "The Light of Other Days". They had Bucky balls as the key to a micro wormhole generator that could look back in time! Talk about exciting potential!
I was still in highschool when everyone was hyped about graphene battery technology. I have a job, a wife and a kid now.. I'll probably be a grandpa before we see this technology in consumer devices
@@PemboCycling hilarious enough, we further away from Fusion than graphene. like you can buy graphene, it exists and it is here now... is just expensive while fusion... well we still can't make it self sustaining, much less extract energy from it
0:11 The conductivity of a material doesn't have much to do with the surface area, but it's about free electrons available in the conduction band of the material.
At his point, for my sanity, I just assume that all graphene related technologies will not happen in my lifetime. Better to be pleasantly surprised than constantly disappointed.
There already is a battery chemistry much safer and more resilient then nickel magnesium cobalt or nickel cobalt aluminum. Lithium iron phosphate. The patent on those expired so now everyone in China makes them. You can get them in base models of their EVs as well as the Chinese made base tesla model 3. Pack density is comparable to nmc and nca batteries due to omission of liquid cooling.
I used ultra caps in my car for my stereo lol... yes, they were extremely powerful... I loved them 😎 won 1st place in competition. I always knew they would be the future.
Graphene is one of those technologies that, if delivered on, will solve a good chunk of humanity's problems. If people focused on it as much as they do on marvel movies or johnny depp then we might actually be somewhere right now.
It won't solve many problems, rather, it'd just introduce a new level of commodity for those who have the money. People like to believe these inventions are almost magical when in reality it is just one of the many technologies being researched on until one of them takes over and the rest are forgotten, it always happens. Also there is not a single advantage of the average Joe knowing or trying to "focus" on the existence of these things, as it wouldn't make a change nonetheless
Graphene, as joe said; has been talked about ad nauseam for years. I vaguely recall hearinv about it when i was in high school and i graduated almost 15 years ago.
@@javierflores09 Commodities are often some of the least valuable materials on the planet, because they’re just that, commodities. Yes, there are many expensive commodities, but the useful ones are relatively cheap, due to the feedback loop inherent there. Thats why most businesses do all they can to avoid their produce being a mere commodity. If graphene becomes very useful, it sill be because it has gone down in price dramatically. If it doesn’t, then its not that useful.
I rarely comment however when I do, it is because I enjoyed the content. Honestly, the best part, that provided light to my morning, was the puns and dad jokes. I don't know why but this video would not be as successful without it. Thank you for all that you do!
I'm sorry Dawn but I must disagree with you. I don't care for Joe's puns or jokes I find them lame at best. I do enjoy all of his videos and never miss one and I like it when Joe goes off on one of his tangents but I don't think he is not funny.
It’s Joe’s personality and ability to make the content interesting that makes the channel successful. His humor is part of it. Even if not everyone loves his humor, it’s part of his personality, and I doubt many people who find Joe off-putting watch many of his videos.
12.5 times the cost for graphene doesn't actually sound too bad. Depending on the device, if I could spend 12.5 times more for a battery that charges extremely quickly and holds a large amount of energy, I'd go for it. Though I suspect that there would be a ton more factors to consider, each of them potentially adding to cost along the way
I am super excited about this. The big question is how many charges until they reach end of life. The price tag would be so worth it if the charged fast and say quadrupled battery life while being recyclable and made of plastic, total win!
The composition is just graphene and aluminium so I don't think it has recharge cycle limitations. GMG CEO stated that the theoretical upper limit of the pack density is about four times Tesla's current batteries and 60 times faster charging. Crossing fingers that they succeed in bringing to market batteries with even half the theoretical performance, that will be game-changer
I love the opening with the onsite tennis court. You could have just used some stock footage like 99% of similar channels. We notice these nice touches and they elevated the quality of your above so many other channels.
Two guys from my school knew there was a kind of shutdown switch for the science classrooms, so they put paper clips into the top and bottom of the sockets and then flipped the switch, making them all explode at once. Joe's just reminded me of that 🤣
there's a saying in sports training that an overnight success usually takes about 10 years. While the period of preparation varies in other fields, the same principle is pretty universal. There was a time when steam engines were mere curiosities. And then they had a few niche applications. And then we all know how that turned out. Same with cars, computers, and mobile phones. Or how the fusion naysayers shamelessly update their derogatory joke from "50 years away and always will be" when I was a kid, to "30 years away" for a while, and now say "fusion is twenty years away and always will be" without any sense of irony.
@@edwardfletcher7790 just looked it up and it sounds electrical safety switches are the same thing as fuse boxes... in which case the school would have had them, but it wouldn't stop a spark and pop from the turning on of the outlet while the paperclip is in.
@@baggaz167 I'm not sure what he's calling safety switches. If he means just the breaker or a gfci receptacle. Either way you are correct they would not stop the receptacle from going bang. The electric would just be shut off immediately after the pop occurred.
I shake my head every time someone says quote-unquote and then they say the sentence they want to be in quotes. You are the only person that I have seen that does it the "right way" @ 11:12. You say quote, then you say your sentence, and then you say unquote. Keep up the good work Joe!
I think graphene batteries would be the equivalent of a "killer app" for electric-alternative adoption. EV cars, for instance, I've argued won't replace gas-automobiles in America until we have a solution for "refueling" at the same speed as someone would expect to spend time at a gas-station - and this could be it. Even for low-capacity battery storage, if recharge time can become near-negligible you would see a huge increase in demand and also a huge interest in suppliers of electricity (since they should be seeing revenue potential from that too; literally selling electrical energy hand-over-fist to repeat customers).
The fact that they are actually making batteries already is super encouraging! I feel like a lot of these promising technologies never leave the lab, and even if this never progresses beyond the 1.7v coin cell, that's still awesome! Anything we can do to reduce our dependence on slave labor is something we should absolutely do
If the cell can be made thin enough, just combine two cells into one coin cell package to have a coin battery of 3.4V. That said, there are some devices that use alkaline coin cells, that have the same 1.5V as regular AA and AAA batteries. (Obviously less watt-hours because there is less material, but those devices _do_ exist.)
I'm not one who gets optimistic often, but once a technology gets to the point it can be used in niche applications that really need it despite the extra cost, unless there's some hard limit to how much of it can be made such as if it requires a rare element, the manufacturing process often evolves quickly and the price drops. I think there's a pretty good chance we're about to have another explosion of battery technology like when lithium ion hit the scene.
Imagine if they had adopted the electric car instead of ICE cars. All those years of lithium mining, we might now be pondering all the oil in the ground as a more abundant source of energy.
I mean, there's still this wonder material Germanium, which can be made in hexagonal shapes (hexagonal SiGe) to emit light - directly inside a chip, allowing for laser emitting chips for communication or do calculations with light. SiGe can also be used to create bipolar transistors ... so I guess we could make tri-state processors with them or reduce the size of the current processors. And also Germanium is much "faster" than silicone based chips, as the electrons flow a lot faster through the material, and thus you can archive more clock cycles.
@@Megabean it's also not science fiction, silicon was just chosen in the early days because of the toxicity of Germanium (in the used GeAs form) and the more easy manufacturing. The Cray-3 has actually used them, because they were faster back then. But they company got bankrupt while building the Cray-4 and also the 244 MHz of the silicone technology back then has seen massive improvements, because of further miniaturisation. But as we really seem to approach the limits what's possible with silicone, we may just wanna look somewhere else. :) There's pretty new research on this topic from 2021, which claims Germanium could be used to reduce the amount of transistors be 85%, which could basically also cut down the energy consumption by a similar factor.
Semiconductor photonics are limited in size by the wavelength of the light used to power them, making 5nm features impractical as you would need an EUV/Soft X-ray source of light, needless to say you probably don't want photons with that much energy flying around your nuts. This is a very well studied field, with a lot of applications, high density ICs will require a few breakthroughs that are not on the horizon now as far as i know though.
@@RubenKelevra I've heard of research projects (but haven't heard of any results yet) of trying to use the diamond allotrope of carbon instead if silicon for ICs. Theoretically much higher temperature resistance, lowering the need for cooling electronics. I don't know about how quickly diamond based transistors can change state vs. silicon or germanium.
A space elevator is one of those inventions that's never going to happen but a lot of good things are going to come out of us trying to learn how to make it happen
Thank you for this month's "battery changing breakthrough technology". I promise to hold my breath until the first battery using this technology comes off the production line.
@@aceroadholder2185 In October of 2021 GMG signed a deal with BOSCH to build a factory for G+AL batteries. It is currently being built in Brisbane. It's real whether you like it or not.
@@silverywingsagainIt's also not really out on the market yet. Unless you see a product sold with a graphene battery and it actually IS a REAL graphene battery AND it works without too many weird issues, please don't hold your expectations in the sky.
4:09 Graphene is like that gifted kid who graduated high school at the age of 12, was forced by his/her parents to go to an Ivy League college, earned a PhD by 18, moved away from parents and ends up working part-time saying mainly "Would you like fries with that?"
When it comes to "on the horizon" materials science I'm most excited for the combination of protein folding and cas9. Mastering protein synthesis and production could lead to some pretty crazy stuff!
INTERESTING and entertaining, as are all your videos. I am like you; whenever I hear the words "battery" and "breakthrough" in the same sentence, I just immediately think of something like Solid State Batteries which look good on paper, and can power a car for a thousand miles, but can't power themselves off the lab test bench and INTO a car. The battery making it to actual commercial use will thus forever be "three to five years away". I call this the breakthrough horizon because it recedes as you approach. BUT, because you are awesome, I listen, learn, and enjoy, and adopt a "wait and see" attitude. All good wishes.
SSB are more than lab tech. Though not yet mainstream, I am aware of them being used in transportation (buses). They may not be coming out with a bang, but I think they're for real.
Sigh. You had me until the whole Rio Tinto bit. A few years ago They blew up an aboriginal cave art site in Wa that was over 30 thousand years old that crapped all over the Lascaux caves in France. Not because they needed to but because they could. After taking a total bath in the ASX over it the CEO said something like “Ahhh yeah, we probably shouldn’t have done that, my bad.” And resigned with an eleven million dollar payout. I was working an iron ore mining site nearby at the time and even those of us that have made a living from this thought it was a step too far. RT are like literally the last people on earth that should be put in charge of a nascent technology like graphene.
when I left the semiconductor industry, they were just commercializing Atomic Layer Deposition on silicon wafers, at the rate of regular IC wafer production
The graphene that Graphene Manufacturing Group produces for these batteries does not cost $1000 per kilogram. It costs closer to $2 per kilogram! Amazing stuff they are doing here
"Tech Nerd Stiffy!" LMBO 🤔😆🤣 I Love every video you & your team produce. Always educational, funny, & overall heavily entertaining. I hope that You & Your Family are doing great, staying safe & healthy Joe. Cheers, Stephen W Vernon BC 🇨🇦
Hi Joe, just for your info, there is a company that is already manufacturing graphene based supercap energy storage modules. The company is Kilowatt Labs, Inc. , a US corpration with factory in Dubai, UAE.
The fast charging of graphene could open up the practical possibility of in road inductive car charging. Like how some busses charge at bus stops, only while in motion. At present that's not practical, but with fast charging you'd only need a charging road segment periodically placed.
I would add about graphene patents. The number of patents per year has recently peaked and this is an indicator that (as in other historical tech) corelates to successful commercialization sooner rather than later. I'm betting on this being the decade we start seeing significant graphene technology disruption. Check out the data and come to your own conclusions.
This would almost allow regenerative breaking to fully charge the battery so you would require a much smaller battery. With the weight reduction you would also have better range.
Alternating Current runs on the surface of a conductor. This is called the skin effect and effectively increases the resistance of the conductor. Direct Current, which batteries deliver, runs through the bulk.
This would work great on an electric bus, wouldn't need to think about trolley buses you could just have it recharge at every major stop, then maybe, along with improving rail infrastructure and portable light weight solutions like e-scooters and e-bikes, we could eliminate the need for cars almost entirely, which is by far the best solution to making our lives greener and our cities more livable, especially for those who cannot afford to invest in expensive, space wasting cars.
@0:13 correction: electrons can move throughout a conductor's cross-sectional area, not just the surface. *There is a surface tendency at high frequency called the skin effect, but with DC and AC power supply currents, this is negligible.
Ions and Igens and Ears oh my! Illarious,H! Thanks for the vid, always enjoy them. So many use cases for graphene, always interesting to see the progress being made that isn't always available for study, patents and such, my hope is the the technology will lead to some answers in quantum application.
Manchester University in the UK spent a fortune researching Graphene and the cost of production is an serious road block issue ... but also one guy found a way of using Graphene to convert sea water into drinkable water without massive damage to the eco system. That could be a big thing in the future.
That's why I love this channel. I too was a gifted child with a lot of potential that ended up doing nothing with it. Too many interesting things to learn and unable to focus on just one. I don't even have a youtube channel.
The thing that worries me the most when I consider buying a battery-powered car is: ... out of many times can I charge the battery before it is used up and need to be replaced? It's not cheap to replace the battery pack in a car ... 😥
Imagine giant underground batteries storing energy from renewable sources or a large house battery that has the same purpose. And imagine the batteries come from aluminum and carbon. Some hope for the future. And we need that right now.
One year on, have things gone anywhere? last time I checked we still don't use graphene batteries for anything. Seems like another year has passed and still the use of graphene is very much reserved for the future.
"battery technology is evolving so fast" - dont know about that. I remember some 10 years ago, i was reading about different battery technologies being developed and there were some real amazing promises done that within 5 years time things will change dramatically. 5 years later, in 2017, I've read other articles about battery technologies which were amazing as well and they were supposed to change the world in about 5 years time. Now, another 5 years later, we are where? Yet another 5 years before some major breakthrough will happen? and then what? Another 5 years?
Well to be fair, my wireless headset from ten years ago was charged for 3 hours and it was heavy as hell in comparison to my wireless headset today which holds literally 30 hours, charges in half an hour and is light as a feather and only costs a couple of hundred euros. I think there is definately some progress there. I think with other electronics the issue is just that just as we perfect the battery the electronic itself starts using even more power as its more powerful so in the end it feels like there was no progress.
@@jurgenkoks9142 Yes, batteries did definitely improved from what they were 10-15 years ago, its just the main device what we all have and where we all need more capacity than it has is a mobile phone and 15 years ago mobile phones lasted for a week without problems, so it feels that there is no improvement in batteries since now we need to charge our phones every single day.
0:13 electrons does not move on the surface of a condctor. Electrons are bound in to the conductor itself just like a pipe of water would transport water but the surface of the pipe is also transporting water. A bit away to say surface, that means the more surface the more electrons. In reality we do not use radiators as wires. Because its not about surface,
There is another graphene battery on the market. Right now they only sell battery packs, but they charge quite a bit faster than a comparable lithium ion battery. Plus a new concrete that uses graphene as a component and has increased strength compared to ordinary concrete. It may be taking a while and hasn’t become a wonder material yet, but graphene is starting to arrive at the market and it does have a significant quality advantage even using lower grades compared to existing materials that can allow it to gain a foothold in the quality/luxury market needed to get more money in R&D to start producing it cheaper and at the higher qualities and larger sheet sizes we would need to start unlocking the wonder material aspect of graphene. From a historical perspective we should also remember the first synthetic plastic was made in 1907, but didn’t become the ubiquitous material used for disposable items until the 1950s-1970s. Graphene was discovered in 2004. Even if it takes until the 2050s, it seems likely at this point that graphene will be a game changer. I’m personally hoping that it’ll become big in the 2030s. The 2020s seem more likely to be the era where graphene becomes a niche product like lithium batteries were in the 2000s. If so then graphene may become big in the 2030s, and a wonder material in the 2040s if we’re lucky.
I think it would be interesting if you reacted to your videos pre-pandemic. So much has changed, esp what our future what going to look like, vs what actually happened.
joe by no means are you a mid-tier content creator. imho you are probably the best science communicator there is. i am always dumbfounded when i'm reminded you only have 1,3M subs. your production value and content is worth at least 8M-16M imho. and i'm not exaggerating!
It's something to get excited about! The price is not that much of an issue, because that is the same with every new technology. We all remember the time SSD's hit the market at a price of around $1/MB... they were way too expensive to replace those HDD. Now, that's practically all we use at a fraction of the original cost. Looking forward to this new technology and I'm also optimistic, since in Western Europe we all went into a cramp to look for renewables so we can stick it to Russia... It feels like we went for a stroll for decades and all of a sudden we ramp it up to 6th gear.
You mentioned a space elevator being possible. What about one servicing the Moon? Take everything we think we know about building one here on Earth but do it up there: 1. go capture an asteroid 2. drag it to the Moon and place it in a geostationary orbit 3. lower a grapene weaver to the surface all the while making a cable 4. anchor the cable 5. climb back up the cable making it stronger etc. Surely, having a Lunar Space Elevator would lower the costs of getting people and materials to and from the surface to a minimum. Wouldn't it?
I fly a lot of R/C airplanes and have been worried about the Li-Po batteries while charging. Then after a flight , they are really hot and get puffy. I finally purchased a set of Graphene batteries and WOW ! A big difference. longer flight times and they don't get hot.
2 points just by watching the first minute and a half. A. Electrons don’t move in a conductor, charges do. B. 99% of energy (haven’t checked the numbers but somewhere in that neighborhood) is stored in height differential energy storage. Not chemical. We are definitely not a lithium ion powered world
4:20 Samesies! Gifted school, only to become and alcoholic. "You have so much potential" they told me... I strongly dislike the way my life has unfolded. And it makes it worse to think that everyone thought I should easily be doing well, when in reality, I'm struggling just to feed myself
I just completed a 6,000 mile US road trip in my 2021 Model 3 SR+ Over 13 days of driving (July 10 through July 31, 2022, with time in Kentucky) from Sacramento CA to Louisville KY and back (with numerous side trips), I drove nearly half what I drive in a year. Shortest distance ~300 miles. Longest drive 650+ miles. Average ~450 miles. The final analysis: Wow. This is definitely a road warrior vehicle, despite so-called “conventional wisdom.” I am still plugging in metrics and numbers, but I estimate about 60 charging stops. In all those stops, I only had ONE 5 minute wait, at Glenwood Springs, CO. One. 5 minutes. I’ve waited longer in a grocery store line. I drove through and charged in major cities (LA, Amarillo, OK City, Little Rock, Memphis, Nashville, St. Louis, Kansas City, Denver, Salt Lake City) and countless small towns and wide spots in the road. Typically, I was either the only one there or one of two Teslas. My typical stop was 20-25 minutes. Enough time to have a short walk about, use the bathroom, grab a bottle of water, and then get back on the road (the breaks, and auto pilot, assured I’d be rested and relaxed after hours of travel). Weekdays, weekends, rush hour, nighttime, huge supercharger (50+) or small (4), interstate or blue highway… I drove and charged through them all. No cherry picking. ~60 superchargers. 6,000 miles. 13 days of driving. In July 2022. One wait. 5 minutes. I can’t speak for others. But a complete success in my book.
Teslas are fun to drive, but they suck at long distance travel. Per your account, you drove 6,000 miles with 60 supercharger stops. So 100 miles between stops. This means you drove about an hour and a half on the highway (70mph speed limit), stopped for 20-25min to charge up, then another hour and a half of driving, then another 20-25min stop, and so on. Your average 450 miles trip had 4-5 stops of 20-25 min each. I used to drive a 400 mile trip from Ohio to DC (roundtrip 800 miles) every two weeks that took me 6 hours with one 10min stop in West Virginia (no need to refuel during the trip). With a Tesla it would have been 7.5 hours.... or about 25% longer. This massive waiting period is a big problem: if truckers need to spend 25min at megachargers for every 100 miles driven, EV trucks are DOA. EVs are much better as daily commuting vehicles though. The average commuting distance in the US is 40 miles roundtrip, which any EV can do w/o needing a charge. But long distance? I just don't see most Americans putting up with it, to be honest. I might not care when I'm retired, but not now. Thank you for sharing your experience with us. I really appreciate it and I'm happy you enjoyed your trip.
@@lukeearthcrawler896 You’re applying my experience universally to all EVs. That’s erroneous. I am driving the poor man’s Tesla with the shortest range. My experience is not applicable to EVs which have a longer range. Also, while you appear to have zero experience driving an EV, I have 50+ years driving ICE vehicles. Many different types of vehicles, over many different trips (including many cross country trips), in many various types of situations. So I’d consider my recent EV cross country trip experience a valid comparison with an experienced driver of ICE and EVs. Your comparison appears to be hypothetical and based on conjecture. I did enjoy my trip, very much, thank you. And I’ll be taking more of them in my Tesla. Or my wife’s VW ID.4 PRO! Our family took a 1,500 miles trip in that vehicle to the North Rim of the Grand Canyon and Zion National Park. These summer trips in our EVs were delightful, went without hiccups, and are the first of many to come. Goodbye ICE!
@@ezpoppy55 Thank you for the reply. The ratio of time travelled (or miles driven) to time wasted at superchargers depends only on the charging speed, not the battery size: if the battery is twice as big, you go twice the distance but also have to wait twice as long to recharge it. This is how physics and math works. There are many videos on RU-vid about EVs range. In particular, a team drove a Rivian in Colorado and fully charged it towed a camper uphill 80 miles before running out of battery charge. So a little bit over one hour of driving, followed by long charging session. This will never fly for semis. So I stand by my assessment that EVs are great commuter vehicles but they are not all that good as long distance haulers. Yes, you can make it work, IF you have the time. If you're retired and don't care, sure, take your sweet time. But commercial vehicles? Time is money as the old saying goes. Ask any trucker if he's okay with 20-30% longer trips compared to an ICE truck and see what he says. I'm not bashing EVs or your experience. I'm merely pointing out the serious shortcomings of EVs. Elon is aware of this, which is why the Tesla Semi is nowhere to be seen on the road, although it was announced 6 years ago.
Latest testing data has demonstrated a calculated energy density that has increased by 93% from 150-160 Wh/kg to 290-310 Wh/Kg since the last battery update on the 22nd of June 2021
"Li - on's share of the market". I clicked on this vid _after_ logging out to go to bed and literally signed back in to give it a thumbs up just for that! Good one!
There is LIG laser induced graphene and flash graphene. Both can produce high-quality graphene. There is, of course, that one crucial issue is that it possesses no band gap. That is its key drawback. Maybe the answer is graphene quantum dots and/or structures.
I really hope Graphene isn't the next fusion where its always just a few years away. I remember learning about it for the first time when our house was tented. We got sent to a hotel and there happened to be a brief clip about it on the TV when I turned it on. It seems like it could become an amazing technology if someone makes a more efficient way to manufacture it.
Graphine is a further example of how energy density in batteries has a long long way to go... especially when you consider that an energy grade nuclear fuel rod the size of a coke can power nuclear submarines for 80+ years !!! ... Awesome Video !
Lithium ion is also redundant because all batteries deal with ions. You could rename lead acid or nickel cadmium as "lead acid ion" or "nickel cadmium ion"
Joe I think a really good video could be a overview of experimental battery techs over the past few decades, explaining how long they spent in development, their capabilities, and if they ever made it to the market in any substantial way, and if they didn't then why did they fail? Seems like every year I hear of one or more new revolutionary battery tech(s), but seems like nothing ever makes it to the market.
There's a lot of challenges to making it work. The first major hurdle is funding, they have to be able to fund their research long enough to develop mass manufacturing procedures then build the plant. The second major hurdle is actually developing a mass manufacturing process which often fails for one reason or another. The third major hurdle is advertising this is true both before the battery is ready when they are trying to attract funding and after (assuming they get that far) to actually sell some batteries. Obviously all of these are interconnected and I'm sure people can find other big hurdles that have to be surmounted but I think these are the big 3.
Joe, You should do an episode on how excessive use of puns are sometimes a sign of brain damage. I have a super smart friend that just cant help himself to make pretty clever but exhausting puns way way too much. He has had several concussion's in his life and we are pretty sure he has this condition.
I'm (obviously) an auto detailer. One of the newest 'breakthroughs' is graphene waxes. According to the latest information I have they're actually just adding graphITE to their existing products and claiming it works better. Somehow.
