While lithium extraction technologies generally focus on ways to get the essential metal out of the ground, there's another source to mine: existing batteries that no longer work. A new technique could now make that process economically viable.

If this truly works, that would be fantastic news, but getting clean lithium out of a used battery that has been degraded and the lithium has become contaminated sounds extremely complicated, so I'm still a bit skepical on the feasibility of it.

    The process honestly sounds to me a little bit like decaffeination, which also feels like witchcraft to me. So it might work!
