MANUFACTURING METHOD OF CATHODE ACTIVE MATERIAL AND LITHIUM BATTERY THEREBY

摘要

PURPOSE: A method for manufacturing positive electrode active material powder is provided to produce sodium chloride molten in water as by-products using metal chlorides as raw materials. CONSTITUTION: A method for manufacturing positive electrode active material powder comprises the steps of: mixing a metal hydroxide precursor with lithium salts, wherein the metal hydroxide precursor is obtained using metal chlorides as a raw material, ammonia as a chelating agent, and sodium hydroxide as a coprecipitator; and sintering the mixture in inert gas or air to prepare xLi_2MnO_3·(1-x)LiM'O_2 powder. In chemical formula, X has a value of 0
