Abstract
In a method for regenerating a lithium precursor, an electrode active material mixture collected from a lithium secondary battery is prepared. The electrode active material mixture is reduced in a dry rotary heating reactor to form a preliminary precursor mixture. A lithium precursor is selectively recovered from the preliminary precursor mixture. Recovery yield and selectivity can be improved using the dry rotary heating reactor.
