ELECTRODE ACTIVE MATERIAL FOR NONAQUEOUS SECONDARY BATTERY, AND METHOD FOR MANUFACTURING SAME

WIPO Patent Application WO/2019/026690

A1

The purpose of one mode of the present disclosure is to provide an electrode active material capable of constituting a nonaqueous secondary battery with excellent output characteristics, and a method for manufacturing the electrode active material. A first mode is an electrode active material for a nonaqueous secondary battery that contains: alkali metal/transition metal composite oxide particles; graphene in which positive holes have been formed; and an anion. The electrode active material for a nonaqueous secondary battery is manufactured by obtaining graphene in which positive holes are formed by bringing a graphene raw material into contact with a two-coordinated boron cation, and bringing the graphene in which positive holes have been formed into contact with the alkali metal/transition metal composite oxide particles.
