Cathode active material coated with resistance-reduction coating layer, and all solid-state lithium secondary battery using the same

摘要

In a cathode active material coated with a resistance-reduction coating layer for preventing formation of a resistive layer, which has a cathode active material and a resistance-reduction coating layer with which a surface of the cathode active material is coated, the resistance-reduction coating layer contains substantially no fine particles of the cathode active material.
