▎ 摘　　要

NOVELTY - Preparing three-dimensional silver nitrogen tungsten/reduced graphene oxide hydrogel electrode material involves mixing silver nitrogen tungsten solution and graphene oxide solution uniformly to obtain mixed solution. The mass ratio of silver nitrogen tungsten (AgNW) to graphene oxide is (0.1-10):(5-250). The ascorbic acid is added to the mixed solution. The reduction reaction is performed at 50-100 degrees C for 8-15 hours, and then dialyzed to obtain final product. The mass ratio of ascorbic acid to graphene oxide is (0.1-0.5)g:(5-250)mg. USE - Method for preparing three-dimensional silver nitrogen tungsten/reduced graphene oxide hydrogel electrode material used in the field of supercapacitors (claimed). ADVANTAGE - The method enables to prepare three-dimensional silver nitrogen tungsten/reduced graphene oxide hydrogel electrode material that has excellent charge transport characteristics, simple preparation process and good application prospects in the energy field.
