Much grateful for all your EV videos Sir. IMHO, Sodium ion battery is already a Perfect battery. Considering salt is an infinitely endless raw material available everywhere. Sea water desalination problems of where to put the extracted salt can possibly be solved thru this. That said, the trick to maximize adoption of Salt ion batteries maybe to go for trade offs. Salt ion batteries with shorter lifespan but much cheaper would allow more to buy EVs. This way, if ever recyclability is already possibly maximized, battery manufacturers will profit more by selling more batteries. This is comparable to China model of selling quantity over quality. Though it doesn't mean the salt ion batteries be poor quality, just traded off long life to lower price. With such strategy, much more salt ion battery manufacturers / recyclers could come up boosting the economies of their localities. Salt ion batteries on massive scale being charged by renewable energy could then compete with other fuels like petrol and coal. Again, I think the secret lies in trade off rather than wait a very long time to perfect this technology.
Maybe the solution in the future is some hybrid combo of sodium ion and lithium ion batteries plus increased deployment of fast chargers. The goal is to get a combined real world capacity of atleast 330-460 miles, regardless of condition or weather. We may not be there today but hopefully sooner or later.
Keep on with the battery tech updates, its very interesting. Long lasting, high density energy storage at low cost is the whole game and it is happening. Thanks Sam
Viking is a Renaissance man or polymath. I am a Chemist and love watching his battery chemistry videos. Most EV content providers can't touch these subjects.

Sodium is much more reactive with water. It is much heavier than lithium but it only carries the same one positive charge. For cars lithium must be better but for stationary batteries sodium is good.
I think you meant to say negative charge. The periodic table tells us all we need to know about Lithium and Sodium. Lithium is small and light, sodium isn't.
@@davidbrayshaw3529 No. Group 1 elements lose an electron - the only one in their outer shell - so the positive protons outnumber the negative electrons....creating a positive ion.
@@johnfrancis4401 Now you've got me thinking! If they lose an electron, then yes, they are ionised. If that electron remains in the outer shell then the atom is stable, I believe. I am open to correction. My last physics class was in the mid 80's.
@@davidbrayshaw3529 No.....sorry. Ions are stable because they have full outer shells. But to achieve full outer shells the atom must gain or lose an electron or two or three. Chemistry...circa 1965
All alkali metals are reactive, which is why they are useful in batteries. They are dissolved in the electrolyte which in lithium's case is flammable. It's this burning of the electrolytes that sustain a runaway reaction, not the reactivity of the metal itself. The two electrolyte's being used in modern Sodium-Ion batteries are not flammable and do not easily burn. This inherently should make sodium-ion safer, but time will tell. However, either type of battery has been proven over and over again to be significantly safer than gasoline and results in roughly 1/60th the amount of fires for any given vehicle.
I love your videos, although I am skeptical about the future of EVs. Having said that, I think the use of the term "doping" to describe how the Germans are increasing the potential of sodium batteries is somewhat unfortunate and conjures up memories of when East German athletes were doping to improve their performances in the Olympics during the Cold War.
In time AI will solve the issues and the researchers just have to work out how to make the stuff AI suggested. In simulation you can try every combination that exist easily.
In my country India we need a storage battery system for Solar setup. Lead battery technology which is being use now and command 99% of the Indian market is pathetic to say the least.
Irrelevant. We are talking about doping here. That means miniscule amounts. Anyway at the moment nobody much is actively exploiting scandium. When they do the price will plummet. Aluminium started out more costly than gold but it is now a plentiful inexpensive commodity.
@@rogerphelps9939 Minuscule amounts on a film that is nm thick adds up pretty quickly. Aluminum was costly due to refining costs, and after a bit more digging you are right. It is an under utilized element whose cost is only high because no one knows what to do with the stuff outside of aluminum alloy production.
I highly doubt it. Sodium is more than 3 times the molar weight of lithium and carries 11 electrons in its outer shells to lithium's 3. It is going to have very little practical application in transportation. Where it will benefit transportation is by freeing up lithium that's currently being used in stationary batteries. You might see it used in tuk tuks and golf carts, but that's about it.
If you look at a chart of battery improvements over the past 20 years, you'll quickly see prices per kw have fallen by 60 times(or rather 1/60th original cost), charging speeds in the last 15 years have increased 20 times and battery density has increased by 3 to 4 times. These breakthrough's are most definitely happening, people just aren't paying attention because they're more gradual compounded improvements than sudden one off events. The newer batteries just released by CATL have some serious improvements in density, charging, and pricing so this gradual compounded improvements will continue for the foreseeable future. It isn't just CATL either. BYD and Panasonic have newer batteries coming out in the next few months with some pretty impressive improvements as well.
@@Ryan-ff2db with all those batteries from lab to commercial production it is at least ten years of development and i am been generous with the time frame. Regardless it will be at least 20 years before the grid is expanded enough to cope with the load . What about more remote areas that rely on generators of less than 5mw to power the towns ? Don't say solar because cyclones and cloud cover during the wet season make solar pretty useless Australia is way more than city's
@@randomoldbloke The research in batteries is ever increasing, with more money than ever going into R&D than ever before. 20 years is a ridiculous overstatement but the truth is most of these experimental batteries will never make it to commercial use. However, some will. The next few years will see significant improvements in batteries across the board, just as the years previous, but it all starts at the lab level. Another thing to note, sodium-ion batteries are already on the market and there are almost 30 factories under construction dedicated to Sodium-Ion. Improvements to an existing technology happens a lot faster than inventing a whole new architecture, which is exactly what this video was about. I'm not going to talk about solar as has nothing to do with my comment or the video or even the original comment.
Well they found a way to get rid of the giant pits that take forever to produce a bad product and changed it to high pressure filters which are 99% perfect instead of 40%. Seems way more beleavable. Also BEVs will not be the most use for batterys solar and energy will need A LOT.....
Actually lithium prices are rising. Over-production in china by 91 mfgs led to glut of car inventory and pause in buying li. What you need to know is that lithium price is below production cost...... Way below for long-term sustainable lithium production. It's just going to lead to a cyclical high swing because of the pause in the supply chain development.
