▎ 摘  要

NOVELTY - The preparation method of nano-titania sheet-coated graphene anode material of lithium-ion battery involves preparing graphene oxide using Hummer method, dispersing graphene oxide in isopropanol, ultrasonically peeling to form graphene oxide suspension, adding certain amount of diethylene triamine to graphene oxide, stirring, adding tetrabutyl titanate, stirring, placing in a sealed autoclave, solvothermal reacting, washing the solvothermal reaction product with ethanol, drying, and high temperature treating under a protective atmosphere. USE - Preparation of nano-titania sheet-coated graphene anode material of lithium-ion battery (claimed). ADVANTAGE - The method effectively prevents the reunion, and overlapping in the process of reducing graphene, and improves the electronic conductivity of nano-titania sheet-coated graphene anode material.
