Battery recycling is a really important part of this ecosystem, not just to be responsible in closing the loop, but simply to get rid of these batteries; otherwise, at their end of life you're going to have mountains of lithium-ion batteries down the line. This is a post-2025 thing.
The other key thing is, if you're recycling the battery, it doesn't necessarily mean you can use the lithium out of there or the cobalt out of there in a new lithium-ion battery. I think that's kind of a misunderstanding. That stage of taking out lithium and putting it back to use in a battery hasn't really been cracked yet in a consistent way.
There are still challenges to remain, but the Europeans are pushing ahead with battery recycling and the amounts of recycled components reused in a battery, just because they want to set the tone on making a responsible supply chain. I think right now that's where we stand.
