LITHIUM RECOVERY METHOD

The present invention relates to a method for efficiently recovering valuable metals from end-of-life waste batteries in a dry smelting manner and, more specifically, to a lithium recovery method wherein a flux and a sulfur component are mixed with pulverized or smashed waste lithium battery cells, followed by melting at a high temperature of 1400° C. or higher, and then a lithium-sulfur compound (Li2S) volatilized therefrom is obtained.
