▎ 摘　　要

NOVELTY - Preparing lithium titanate graphene electrode material comprises hydrothermally reacting lithium titanate and graphene oxide to obtain composite electrode material, where the lithium titanate is Li4Ti5O12 prepared by Li2CO3 and TiO2 ball milling method, and the mass ratio of Li4Ti5O12 and graphene oxide is (70-90):(10-30). USE - The method is useful for preparing lithium titanate graphene electrode material. ADVANTAGE - The method can avoid the direct contact between the cathode electrode and the electrolyte, improve the compatibility between the electrolyte and the cathode electrode, can increase the conductivity of Li4Ti5O12, provide more intercalated lithium sites, and reduce the irreversible capacity, at the same time, the introduction of graphene can also promote the diffusion of lithium ions and reduce the resistance of the SEI film, and improves the high/low temperature performance of the battery. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a lithium titanate graphene electrode material prepared by the above-mentioned method.
