Abstract
A method for producing a lithium composition capable of suppressing the generation of polysulfides is provided. The method for producing a lithium composition includes a first aqueous solution forming step of forming a first aqueous solution by reacting iodine with a reducing aqueous solution containing calcium oxide, formic acid, and water under a condition of a pH of 5.5 or more and a pH of 10.21 or less through heating, a second aqueous solution forming step of forming a second aqueous solution by adding calcium oxide to the first aqueous solution, a third aqueous solution forming step of forming a third aqueous solution by adding lithium carbonate to the second aqueous solution, and a Li2S forming step of forming the lithium sulfide (Li2S) by sulfurizing lithium hydroxide (LiOH) to form lithium hydrosulfide (LiHS) and then eliminating hydrogen sulfide from lithium hydrosulfide (LiHS).
