非水系二次電池用電極活物質及びその製造方法

Document Type and Number:

Japanese Patent JP7170644

Kind Code:

B2

Abstract:

An electrode active material for a nonaqueous secondary battery comprising: an alkali metal-transition metal composite oxide particles, a hole-doped graphene with an anion. The electrode active material for a nonaqueous secondary battery may be manufactured by a method which includes obtaining a hole-doped graphene by bringing a graphene raw material into contact with a two-coordinate boron cation, and bringing the hole-doped graphene into contact with an alkali metal-transition metal composite oxide particle.
