A new way to reclaim cathode materials used in lithium batteries for use in new batteries

"more efficient than batteries made with newly mined metals... specifically the metals—nickel, manganese and cobalt... under a microscope, particles in the powder had larger pores than metals taken directly from a mine, and they were also less brittle... more porous metals make better batteries because they enable better ion diffusion. They are also less likely to crack after repeated charging and discharging... plans to build a facility capable of processing 10,000 tons of batteries a year by the end of next year"
