▎ 摘 要
NOVELTY - Preparing graphite anode material based on graphene/asphalt, comprises (i) uniform mixing of the asphalt and the oxidized graphene dispersing the oxidized graphene powder in the solvent to obtain the oxidized graphene solution, dissolving/dispersing the asphalt in the organic solvent to obtain the asphalt solution, uniformly mixing the oxidized graphene; (ii) carrying out solvent thermal reaction for the mixed solution, where the thermal reaction temperature is 100-220 degrees centigrade, the reaction time is 6-18 hours; and (iii) filtering sample, washing, fully drying, and placing in a graphitizing furnace for graphitization. USE - The material is useful in the double-ion battery (claimed). ADVANTAGE - The composite electrode material provides higher conductivity at the same time, more anion intercalation site and shorter ion diffusion distance, so as to realize further lifting of double-ion battery characteristics. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: graphite anode material based on graphene/asphalt; and use of the material in the double-ion battery.
