@jamesraymond1158 2 месяца назад

Very clear. It would be helpful to distinguish between lithium batteries and lithium ion batteries.

@louispiper973 Месяц назад

The original lithium batteries contained lithium metal anodes but dendrites/whiskers caused safety issues. Sony brought out the graphite anode with their camcorder and rebranded as "Li-ion" to help distinguish them. Almost all commercial Li-ion batteries use graphite (with some silicon) as the anode. The push to solid state batteries aim to use lithium metal anodes to increase energy density (and suppress dendrites). Hope that helps!

it would be good to consider formats or designs that would make the materials recoverable and recyclable. Perhaps something like being able to unroll the layers the way film was unwound from cartridges so it can be processed....

@Joe-Dead Месяц назад

they are recoverable and recyclable, just right now the cost of recycling is greater than the cost of buying the raw materials for new ones.

@i18nGuy Месяц назад

@@Joe-Dead that is of course true. What I am suggesting is there may be designs that make the materials more easily retrieved, separated and processed to reduce the cost of recycling.

@Joe-Dead Месяц назад

@@i18nGuy you can't. the cost isn't how the batteries are made, it's chemically separating everything at scale. secondly you have to design a battery...to be a battery and that limits choices otherwise you don't have battery or a very poor battery compared to everyone else making good batteries.

Mark, I have some Timex watches to recommend too…when your Casio breaks😊

@knightsljx Месяц назад

The explanation is incorrect. Maybe it's trying to dumb down for the audience, but during discharge, it is the Cobalt that is reduced from Co3+ to Co2+ and in the Li+ intercalates as LiCoO2. The Li does not recombine with the electrons, otherwise there would no voltage. This is a science channel, be precise

@bodilnielsen9760 2 месяца назад

I would love to see a similar video just for Na batteries, which also includes advantages and disadvantages of Li vs. Na and the future prospects. As far as I know the supply of Li might become an issue in the future with the world wanting more and more batteries, so would be nice to learn something about the possible solutions to that :D

@vylbird8014 2 месяца назад

It is likely to become a problem in the future, but right now it's cheap enough to be treated as disposable. You can find free batteries in the street. Every disposable vape contains a reusable lithium cell, but they are so cheap that they aren't even worth the cost of collecting them for recycling.

@DemPilafian 2 месяца назад

Li is *NOT* rare. We have plenty of Li for the foreseeable future, but like most all natural resources it requires capital investment years in advance. The big issue with Li is that the evaporation ponds look very weird and that freaks out irrational far-left virtue signaling pretend environmentalists.

@Dat_Sun 2 месяца назад

I have some large 10-20ah 6s lithium polymer packs that have puffed into circles. What am I supposed to do with them? The local dump won't take them. And I can't find any recycling facilities that take these.

@vylbird8014 2 месяца назад

The 'spicy pillows.' There often aren't any legitimate means of disposal. I sneak them into the e-waste disposal pickups at work.

@Dat_Sun 2 месяца назад

@vylbird8014 Crazy part is I have a few hundred others just waiting to do the same thing. I've been acquiring lipo packs for about 15 years now, most are out of IR balance and of no use. Was used for large scale rc stuff.

@Safetytrousers 2 месяца назад

I went into town to drop my old phone in for recycling. The first place I went to that said it did on the net said they didn't and told me somewhere else to go, that place told me somewhere else to go and that third place didn't do it either. I had to chuck it in the general waste at home.

@vylbird8014 2 месяца назад

@@Safetytrousers Tends to happen. The problem is that the spicy pillow is on the verge of fiery, toxic poof. One good knock and a bit of bad luck and it doesn't just catch fire, even the fumes from the fire are poisonous. Couriers won't carry them without expensive precautions, so it's just not economical. The safe disposal costs are so high that the cells just get passed over until someone is willing to go for unsafe disposal. The lithium isn't the problem - you can make that safe just by exposing it to oxygen for a bit. It's the electrolyte. Organic solvents with fluorine in that form hydrofluoric acid when burned, one of those 'nope' chemicals that is both corrosive and toxic in the extreme.

@Dat_Sun 2 месяца назад

@Safetytrousers Unless I want to plan a road trip, my only option would be sneaking it in the waste transfer place. I placed a 6s pack on a light bulb load for about a week. Disconnected it, and a few days later, it had 15 volts. Still technically dead, but dangerous. I am really concerned about poking holes through these as some say to do before dunking in saltwater.

@DemPilafian 2 месяца назад

It's good that scientists and engineers are working on reducing the carbon footprint of manufacturing lithium batteries, but society's obsession with this issue is wildly misplaced. New EV batteries can have a lifespan exceeding 500,000 km. A LICE vehicle will burn over 30,000 liters of gasoline into the atmosphere during its lifespan. What's more costly: _A one-time fee of $50 or a monthly fee of $20 in perpetuity?_

@Valkyrie9000 2 месяца назад

"Can have" is doing a lot of work here. I "can have" a space station, if I can afford it and can wait ten years. Unfortunately for consumers, they can't afford these batteries, and society cannot wait for them to mature. The solution today, as it was nearly 100 years ago, is replacing the majority of car and freight travel with electrified rail networks.

@DemPilafian 2 месяца назад

@@Valkyrie9000 Contrary to popular narratives, not everyone is poor. Many millions of families can afford nice EVs. Besides, the new budget EVs are pretty cheap and their TOC is actually LOWER than similar class LICE vehicles. Economic progress is the best way to reduce poverty. Nothing is solved by constantly objecting to progress because _"What about the poor?"_
