Graphite is an important anode material for lithium-ion batteries，but the low initial coulombic efficiency，short cycle life，and poor rate performance of natural graphite limit its application.In order to improve the stability of its graphite structure and electrochemical performance，Al（NO3）3·9H2O was used as the aluminum source with adjusting the pH with ammonia water and uniformly coating a layer of Al（OH）3 on the surface of graphite by precipitation method，and Al2O3 coated graphite anode material was further prepared by heat treatment.Compared with the atomic layer deposition method，this method had the advantages of simple process and low cost，better control of the reaction process and lower energy consumption than the sol gel method.When the Al2O3 coating mass was 1.03%，the modified graphite surface was smooth.The Al2O3 coating layer could serve as a preformed solid electrolyte interface（SEI），reducing the regeneration of SEI and the consumption of lithium ions during subsequent cycling processes.Electrochemical performance tests showed that the materials exhibited excellent rate performance and cycling stability during charge and discharge processes.Graphite and Al2O3 coated graphite anode materials with a modification amount of 1.03% were assembled with lithium sheets to form lithium-ion batteries.After 100 cycles of charge and discharge at a current density of 0.1C（1.0C=372 mA∙h/g），the specific capacities were 212.59 mA∙h/g and 354.37 mA∙h/g，with capacity retention rates of 67.99% and 98.59%，respectively.
