METHOD FOR PRODUCING LITHIUM MANGANATE

摘要

A method for producing lithium manganate, characterized by comprising the steps of roughly grinding a manganese dioxide material provided by electrolytic deposition, followed by neutralizing, pulverizing finely the resulting electrolytic manganese dioxide by using a pulverizer in which pulverization is performed by collision of particles themselves, followed by sieving, mixing the resulting electrolytic manganese dioxide powder having an average particle diameter of 3 to 20 mu m with a lithium material, and calcinating the resulting mixture.
