▎ 摘　　要

NOVELTY - Preparation of three-dimensional graphene rubidium phosphotungstate involves (1) preparing rubidium phosphotungstate emulsion by mixing the aqueous solution of rubidium chloride with aqueous solution of phosphotungstic acid, cooling to room temperature and filtering, (2) preparing three-dimensional graphene cesium phosphotungstate by mixing the rubidium phosphotungstic acid salt with the aqueous solution of the graphene oxide, carrying out hydrothermal reaction, cooling to room temperature, removing the solid material and freeze drying. USE - Preparation of three-dimensional graphene rubidium phosphotungstate used in the lithium-ion battery cathode material. ADVANTAGE - The preparation of three-dimensional graphene rubidium phosphotungstate is simple. The graphene rubidium phosphotungstate improves the conductivity of heteropoly acid molecular cluster cell.
