▎ 摘　　要

NOVELTY - Producing a graphene oxide bound with transition metal oxide nanoparticles involves: (a) introducing a carboxyl group on the surface of the graphene oxide; (b) binding a transition metal salt to the carboxyl group of the graphene oxide; and (c) reacting the graphene oxide to which the transition metal salt is bound to form a transition metal oxide nanoparticle. USE - The method is useful for producing a graphene oxide bound with transition metal oxide nanoparticles (claimed). ADVANTAGE - The graphene oxide combined with the transition metal oxide nanoparticles has a high structural stability and durability. The electrode material has high energy density and discharge voltage when used in a capacitor. It also has excellent life, and high charge/discharge cycles. The method can minimize performance degradation. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a graphene oxide in which transition metal oxide nanoparticles produced by the method are combined; and (2) an electrode active material particle for a super capacitor comprising graphene oxide to which the transition metal oxide nanoparticle is bound.
