NOVELTY - A mesoporous lithium titanate-graphene composite electrode material preparation method involves reacting raw material with lithium hydroxide and tetra-isopropyl titanate, polyvinylpyrrolidone as dispersing agent and a membrane and ammonia water as pH value adjusting agent, mixed solution of ethylene glycol and de-ionized water as solvent followed by performing hydrothermal reaction, centrifuging and separating, washing, drying and heat treatment to obtain the finished product. USE - Method for preparing a mesoporous lithium titanate-graphene composite electrode material. ADVANTAGE - The method enables preparing the mesoporous lithium titanate-graphene composite electrode material in a simple and easy manner with high dispersibility, small granule, high charging and discharging specific capacity and multiplying power performance.
