Abstract
In a method for regenerating a lithium precursor, a lithium-containing waste mixture is put into a reactor. An inside of the reactor is replaced with carbon dioxide. Temperature raising treatment is performed on the lithium-containing waste mixture and the carbon dioxide to produce lithium carbonate and a transition metal-containing mixture. The lithium precursor may be recovered with high yield and high efficiency through dry treatment using carbon dioxide.
