Method and apparatus for recycling electrode material of lithium secondary battery

摘要

Lithium cobaltate forming the positive electrode of a lithium secondary battery is subjected together with lithium metal to reducing reaction in molten lithium chloride to produce lithium oxide and to precipitate and separate cobalt or cobalt oxide. The lithium oxide is subjected to electro-deposition in molten lithium chloride contained in a lithium electro-deposition tank provided with an anode and a cathode to recover lithium metal deposited on the cathode.
