▎ 摘　　要

NOVELTY - Preparation of multilayer graphene-ferro-cobalt layered bimetallic hydroxide composite material involves preparing multi-layer graphene solution using expanded graphite by ultrasonic process, and performing hydrothermal synthesis to generate iron-cobalt layered bimetallic hydroxide which is parallel to graphene at the surface of graphene and is perpendicular to graphene at the outer surface. USE - Preparation of multilayer graphene-ferro-cobalt layered bimetallic hydroxide composite material used as electrode material of supercapacitor (all claimed). ADVANTAGE - The method enables preparation of multilayer graphene-ferro-cobalt layered bimetallic hydroxide composite material with excellent super-capacitance performance, by simple process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for multilayer graphene-ferro-cobalt layered bimetallic hydroxide composite material.
