Abstract
A process for preparing LiFeO.sub.2 having a layered rock salt type structure is characterized in that at least one member selected from the group consisting of water-soluble iron salts, iron hydroxides, iron oxide hydroxides, and metallic iron is subjected to a hydrothermal treatment in an aqueous solution containing lithium hydroxide and at least one of sodium hydroxide and potassium hydroxide at 130.degree. to 300.degree. C.
