“The process starts with old batteries being separated and burned to strip away non-metal components. What’s left gets crushed into something called black mass. This is essentially a powder packed with recoverable metals. From there, a water-based chemical treatment called hydrometallurgy pulls the lithium out. One clever distinction in this new process is that the recovered lithium hydroxide actually replaces a chemical traditionally used during refining. This cuts the carbon footprint by about 40% compared to older methods.”
Article also said that previous methods got about 45% of the lithium from recycling.
They are hard to put out, but if you want them to burn all you really need is a safe place to do it. So in a big crucible with some type of fume extraction so they aren’t crazy polluting the air. As long as the heat has somewhere safe to go and there isn’t anything else to catch on fire, burning things is easy.

Dumb question… how are they burning them? I thought controlling lithium battery fires was difficult?

Pretty metal
seems like a significant breakthrough
