▎ 摘　　要

NOVELTY - A porous composite electrode material is composited by porous graphene, nickelous hydroxide and polyaniline, where the nickelous hydroxide is deposited on the porous graphene by binding effect of holes, and the polyaniline is combined with a surface of the porous graphene by pi-pi mutual effect. USE - Porous composite electrode material. ADVANTAGE - The material achieves better oxidation and reduction performances. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing a porous composite electrode material, which involves weighing graphite oxide, adding alkali to the graphite oxide, heating and reacting the obtained mixture under the protection of nitrogen to obtain a porous graphene, mixing the porous graphite with nickel salt and water, carrying out ultrasonic dispersing process, centrifuging the mixture to obtain a solid product, washing and drying the solid product to obtain porous graphene/nickel hydroxide, adding and stirring aniline solution with oxidant solution at 4 degrees C to obtain poly-aniline, ultrasonically dispersing the porous graphene/nickel hydroxide into water to obtain a porous graphene/nickel hydroxide solution, dispersing poly-aniline into water, mixing and centrifuging the obtained solution with the porous graphene/nickel hydroxide solution to obtain a solid mixture, and washing and drying the solid mixture to obtain a porous graphene/nickel hydroxide/poly-aniline composite electrode material.
