LITHIUM SECONDARY BATTERY, MANUFACTURING METHOD OF PARTICLE FOR CATHODE ACTIVE MATERIAL COATING, AND MANUFACTURING METHOD OF LITHIUM SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a lithium secondary battery capable of maintaining high discharge-rate capacity, and restraining degradation of cycle capacity, in one equipped with a cathode layer containing a cathode active material, solid electrolyte, and an electrolyte decomposition inhibitor.

SOLUTION: The lithium secondary battery is provided with a cathode layer containing a cathode active material having solid powder on its surface containing primary particles including crystalline or amorphous lithium-ion conductive solid electrolyte and a crystalline electrolyte decomposition inhibitor, an anode layer, and organic electrolyte arranged so as to be in contact with the cathode active material having the solid powder on the surface.
