I'm a little skeptical—it sounds like the claim here is that we just have some technical hurdles, and we'll need some cheap electricity. Missing from this discussion is an analysis of the environmental impact of recycling and the environmental impact of mining.

By no means am I making claims about how batteries will be recycled in the future, I just think we should base our policy decisions on the science. Recycling lithium batteries is not easy, since they tend to blow up. The main recycling processes either toss them in an incinerator, cryogenically freeze them, or chop them up in an inert atmosphere. Most of them recover negligible amounts of lithium, which is cheap to mine anyway.
