METHOD FOR RECOVERING LITHIUM FROM WASTE LITHIUM BATTERIES

The present invention relates to a method for efficiently recovering valuable metals from end-of-life waste lithium batteries by dry molten smelting and, more particularly, to a method for recovering lithium by mixing ground or crushed waste lithium batteries with a flux including a Ca compound and a sulfur component and melting same at a high temperature of 1300° C. or higher, and then obtaining a lithium-sulfide compound (Li2SO4) volatilizing therefrom.
