▎ 摘　　要

NOVELTY - The method involves preparing graphene oxide by using conventional Hummer process. The graphene oxide is uniformly dispersed in deionized water to form a graphene oxide aqueous solution with a concentration of 0.1-0.7 mg/mL. Metal salt is dissolved in ethanol and ethylene glycol solution. The msalt is mixed with the graphene oxide aqueous solution. A metal current collector is heated to a predetermined temperature of 300-500 degree celsius. Precursor mixture solution is coated on a surface of the metal current collector in a step-and-scan manner by ultrasonic spraying process to obtain graphene-supported metal oxide electrode material. USE - Method for manufacturing a graphene load metal oxide electrode material. ADVANTAGE - The method enables uniformly distributing the graphene load metal oxide electrode material on a surface of graphene with better pseudo capacitance performance. The method enables avoiding use of binders without requiring annealing treatment, simplifying electrode preparation process and easily realizing batch preparation of the graphene load metal oxide electrode material. DESCRIPTION OF DRAWING(S) - The drawing shows a graphical view representing relationship between two parameters of a method for manufacturing a graphene load metal oxide electrode material.
