LITHIUM MANGANESE COMPLEX OXIDE FOR LITHIUM SECONDARY BATTERY POSITIVE POLE ACTIVE MATERIAL, MANUFACTURING METHOD THEREOF, AND LITHIUM SECONDARY BATTERY USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a lithium battery scarcely deteriorate of capacity caused by charging and discharging and having high power characteristic, a positive pile active material capable of obtaining the lithium secondary battery, and a manufacturing method thereof.

SOLUTION: Powder of the lithium manganese complex oxide expressed by general formula, LiMn1-xMexO2(Me expresses at least one or more kinds selected from transition metals and Al), having ≥0.1 μm to ≤0.5 μm average particle diameter of powder particles and existing as a single particle without forming agglomerate constitutes the lithium secondary battery as the positive pole active material. The method of manufacturing the lithium manganese complex oxide includes a complex oxide precursor synthetic process and a heat treatment process.
