Abstract The wet chemical synthesis method of lithium-manganese oxide belongs to the field of inorganic non-metallic material and wet clemistry, and is characterized by that the manganese hydroxide is used as raw material in aqueous solution, in the presence of excess lithium compound the oxidant is added so as to insert lithium into crystal lattice of manganese oxide to synthesize intermediate state Li1 plus or minus XMn2O4, then making high-temp. treatment so as to obtain the invented spinelle type Li1 plus or minusXMn2O4 with complete crystal form, stable structure and uniform component. Said invention is simple in production process, low in cost, can control technological parameters to prepare Li1 plus or minusXMn2O4 with different lithium content, uniform chemical component and phase component and excellent chemical properties.
