METHOD FOR MANUFACTURING SPINEL TYPE LITHIUM MANGANAGE

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing spinel type lithium manganate, by which the high temperature properties of a battery such as high temperature preservation properties or high temperature cycle property is improved. SOLUTION: The spinel type lithium manganate is manufactured by pulverizing electrodeposited manganese dioxide, a neutralizing the resultant manganese dioxide with sodium hydroxide or sodium carbonate to adjust its pH to >=2, mixing the electrodeposited manganese dioxide having >=50 m<2> /g specific surface area with a lithium raw material and firing the mixture.
