▎ 摘　　要

NOVELTY - A vanadium pentoxide composite graphene foam electrode plate preparation method involves adding oxidized graphite and polypropylene into ball mill to ball milling, dispersing the ball-milled mixture into mixed solution of ethanol and water. The foamed nickel in the suspension is immersed. The solvent is evaporated and dried. The foamed nickel into muffle furnace protected by hydrogen-nitrogen mixed gas is placed. The mixture is cooled completely after the reaction, followed by putting the vanadium pentoxide into a muffle furnace for annealing, and pressing the electrode after cooling. USE - Method for preparing vanadium pentoxide composite graphene foam electrode plate. ADVANTAGE - The method enables preparing the vanadium pentoxide composite graphene foam electrode plate in a cost effective manner. DETAILED DESCRIPTION - A vanadium pentoxide composite graphene foam electrode plate preparation method involves adding oxidized graphite and polypropylene into ball mill to ball milling, dispersing the ball-milled mixture into mixed solution of ethanol and water by ultrasonically to form suspension. The foamed nickel in the suspension is immersed. The solvent is evaporated and dried. The foamed nickel into muffle furnace protected by hydrogen-nitrogen mixed gas is placed. The mixture is cooled completely after the reaction. The product is immersed completely after the reaction to obtain graphene foam, followed by adding vanadium pentoxide into toluene by ultrasonically to form a suspension and titrating the toluene dispersion containing vanadium pentoxide onto the foamed graphene and drying, putting the vanadium pentoxide into a muffle furnace for annealing, and pressing the electrode after cooling to obtain final product.
