@SmolderingSauna That's a false argument that the fossil fuel lobby loves to bring up. The reason there isn't widespread recycling of EV batteries is because 99% of all the EV batteries that have been made are still in operation. The batteries typically outlive the cars, and are put to secondary uses for stationary applications.

If you want to ring your hands about battery waste, the US throws out about 54 megawatt-hours worth of lithium battery storage each month in the form of single-use electronic vapes.

I'm coming from a vehicle OEM. Down cycling isn't recycling: we can't decompose EV batteries and reuse/recycle like we can, say, steel.
@SmolderingSauna Sorry, I'm coming from a PhD in chemistry, and that's BS. There is more than one process to recycle the the metals in batteries, and they're all >98% recovery. Atoms are atoms. They're not alchemically trasmuted into other elements.
The reason that they're being used is because they're still good. When they're no longer good, they can be recycled. It's just going to take another decade before we have a substantial need for recycling them. That's not a bad thing.

@Nessussus that's great insight. I recall reading a paper about using magnetic fields to enhance performance of some EV battery cells.

There is so much research into new, innovative ways, to build a better battery and increase performance. I have no doubt that the total carbon footprint of EVs will continue to decrease. Smaller batteries, lighter weight, increased range, faster charging. All good things.
Can you recommend any relevant papers about EV battery recycling? I'd be interested to learn more about that process.
