Improved Systems And Methods For Metal Recovery From Lithium Ion Batteries

Abstract: black mass from disused lithium batteries is leached for recovery of various metals in a process that includes precipitation, solvent exchange, ion exchange, and salt splitting to create multiple product streams for recovery of pure value products. most typically, the process is a closed-loop process and allows for production of metallic cobalt and nickel, emd, and a high purity lithium hydroxide or carbonate product with minimal generation of waste streams.
