POSITIVE ELECTRODE ACTIVE MATERIAL FOR LITHIUM SECONDARY BATTERY AND METHOD FOR PRODUCING THE SAME, AND POSITIVE ELECTRODE FOR LITHIUM SECONDARY BATTERY USING THE POSITIVE ELECTRODE ACTIVE MATERIAL AND LITHIUM SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide lithium transition metal compound powder, when used as a lithium secondary battery positive electrode material, achieving a reduction in cost, an improvement in safety and an improvement in load characteristics of a lithium secondary battery, and also capable of improving high voltage characteristics and powder handleability by an improvement in a bulk density.

SOLUTION: A lithium transition metal compound powder for a lithium secondary battery positive electrode material has a peak at 1,500 cm-1or more and 1,800 cm-1or less in infrared-spectroscopic spectrum analysis.
