Abstract
Systems and methods for recovery of lithium and various non-lithium components from lithium ion battery waste materials are presented in which all components are first leached into a leach solution. Non-lithium components are adsorbed to an ion exchange resin, and unbound lithium passes through and precipitated from the pass through fraction. The bound non-lithium components are then sequentially desorbed and preferably electrolytically recovered as metals.
