From energy.gov :

“Cobalt is considered the highest material supply chain risk for electric vehicles (EVs) in the short and medium term. EV batteries can have up to 20 kg of Co in each 100 kilowatt-hour (kWh) pack. Right now, Co can make up to 20% of the weight of the cathode in lithium ion EV batteries.”

This article is from 2021, so I wonder if it’s maybe outmoded.

I do know that batteries are recyclable, but from what I understand, it’s a difficult, risky, and costly process. Has this changed or have there been any advancements on the recycling process?

The lithium article says something I already knew, that it is recyclable, but that process is extremely difficult and costly. Are there any advancements on this front? And it’s not the recycling of cobalt so much as the horrendous conditions present at the cobalt mines that I speak of. Cobalt mining will have to continue even though we can recycle a lot of what was already mined.

I am concerned about billions of dead lithium batteries and what we’re going to do with them, the (so I’m told) very finite resource that is lithium, and the horrors of the cobalt mining necessary for lithium battery function. Am I out of the loop in thinking these are still legitimate concerns for the future of lithium-driven sustainability? Genuinely asking, not trying to be a dick
