COATED POSITIVE ELECTRODE ACTIVE MATERIAL, POSITIVE ELECTRODE FOR NONAQUEOUS SECONDARY BATTERY, NONAQUEOUS SECONDARY BATTERY, AND THEIR PRODUCTION METHODS

摘要

Disclosed is a nonaqueous secondary battery (100) comprising a positive electrode (155) having a positive electrode collector member (151) made of a metal, and a positive electrode active material (153) composed of a lithium-metal complex oxide. The surface of the positive electrode active material (153) is coated with a lithium salt (158) having an average thickness of 20-50 nm.
