METHOD FOR MANUFACTURING LITHIUM MANGANESE SPINEL COMPOSITE OXIDE WITH ENHANCED ELECTROCHEMICAL FUNCTION

摘要

PURPOSE: A spinel structured lithium manganese composite oxide useful for an active material for an anode of a lithium or lithium ion secondary electric cell is provided to extent a lifespan of the cell at room temperature and above, and to minimize decrease in capacity. CONSTITUTION: A method for manufacturing lithium manganese composite oxide having a spinel structure is comprised of the steps of: providing lithium manganese composite oxide having the spinel structure; mixing a lithium compound and a manganese compound; coating the lithium manganese composite oxide with the mixture of the lithium compound and the manganese compound; and firing the coated lithium manganese composite oxide.
