LITHIUM TRANSITION METAL COMPOUND OXIDE, MANUFACTURING METHOD OF POSITIVE ELECTRODE MATERIAL FOR LITHIUM SECONDARY BATTERY, POSITIVE ELECTRODE FOR LITHIUM SECONDARY BATTERY AND LITHIUM SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To easily manufacture positive electrode materials for a lithium secondary battery having various balances between rate characteristic and capacity. SOLUTION: This manufacturing method of a positive electrode material for a lithium secondary battery is characterized in that a lithium transition metal compound oxide is passed through a classifier to separate particles having large particle diameters from particles having small particle diameters, and the particles having large particle diameters are mixed with the particles having small particle diameters at weight ratios of 0:100 to 100:0.
