NOVELTY - A nickel composite oxide graphene foam electrode sheet preparing method involves adding graphite oxide and polyacrylonitrile into ball mill and dispersing the ball-milled mixture into mixed solution of ethanol and water. The foam nickel is immersed into suspending liquid, evaporated and dried. The foamed nickel is placed into muffle furnace protected by hydrogen-nitrogen mixed gas. The product is immersed in hydrochloric acid, followed by titrating toluene suspension containing nickel oxide onto foamed graphene, placing foamed graphene into muffle furnace for annealing and cooling. USE - Method for preparing nickel composite oxide graphene foam electrode sheet. ADVANTAGE - The method enables preparing nickel composite oxide graphene foam electrode sheet in a cost effective manner. DETAILED DESCRIPTION - A nickel composite oxide graphene foam electrode sheet preparing method involves adding graphite oxide and polyacrylonitrile into ball mill and dispersing the ball-milled mixture into a mixed solution of ethanol and water by ultrasonically to form suspension. The foam nickel is immersed into suspending liquid, evaporated and dried. The foamed nickel is placed into muffle furnace protected by hydrogen-nitrogen mixed gas. The mixture is cooled completely after the reaction. The product is immersed in hydrochloric acid and reacted completely to obtain foamed graphene, followed by adding nickel oxide into toluene by ultrasonically to form a suspension, titrating the toluene suspension containing nickel oxide onto the foamed graphene, placing the foamed graphene into a muffle furnace for annealing and cooling to obtain final product.
