▎ 摘　　要

NOVELTY - Preparation of composite anode involves adding titanium dioxide to organic solvent, ultrasonically processing for 0.1-1 hour, adding graphene material, ultrasonically processing for 0.1-5 hour to obtain graphene/titanium dioxide dispersion, adding anode active material to dispersion, ball milling and drying. USE - Preparation of composite anode for battery. ADVANTAGE - The preparation method utilizes graphene to improve the defect of low electronic conductivity of titanium dioxide, thereby improving the overall electronic conductivity of the anode, and combines the graphene/titanium dioxide with anode material to reduce the degree of polarization and agglomeration of graphene, and facilitates the transport of lithium ions between anode particles, thereby improving the electrochemical performance of the battery.
