摘要： A method for recovering the valuable materials from energy storage devices (e.g., spent rechargeable lithium batteries, especially those batteries using nickel-based or nickel and cobalt containing cathode materials) are described. In particular, the proposed method applies carbonyl technology, also known as vapometallurgy, to regenerate pure materials which can be reused as raw materials for making active cathode materials for new lithium batteries.
