Development of a New Combined Approach to the Synthesis of Complex Oxide Based on LiCo0.5Mn1.5O4

A new method of synthesis of cathode materials based on complex oxides of transition metals and lithium of LiCo 0.5 Mn 1.5 O 4 composition has been developed. A combined approach involving cobalt oxidation by air oxygen barbotage and manganese oxidation by potassium permanganate solution followed by evaporation and heat treatment is proposed. It is confirmed that the compounds ( LiCo 0.5 Mn 1.5 O 4 ) obtained using this approach have high physical and chemical characteristics (particle size, specific surface area). The basic technological scheme of synthesis is presented. It is proposed to recycle and regenerate spent solutions and salts in order to return them to certain stages of the technological scheme, when obtaining the final product. It is noted that minimization of wastes, reuse of reagents, reduction of technogenic load on the environment makes the proposed technology more preferable from the ecological point of view.
