摘    要：综述锂离子电池碳负极材料的研究进展,主要包括中间相碳微球、天然石墨、无定形碳负极材料以及天然石墨表面改性。对天然石墨表面改性是改善锂离子电池负极材料性能的重要手段,通过改性处理,可有效降低石墨电极的不可逆容量,从而使可逆容量和库仑效率有较大程度的提高。由于表面改性天然石墨具有成本和性能方面的综合优势,是今后较长一段时间内,工业化应用的锂离子电池主要负极材料。

Abstract: The latest research advances on carbon anode materials for Li-ion batteries are reviewed.The MCMB,natural graphite,amorphous carbon materials and surface modification of natural graphite are included.Surface modification of natural graphite is an important means to improve the anode material properties of Li-ion battery.Through the modified treatment,the irreversible capacity of graphite electrode can be effectively reduced,so that the reversible capacity and coulomb efficiency have a great degree of improvement.On account of surface modification of natural graphite possess general advantages of cost and performance,in future it will be the main Li-ion battery anode materials in industrial applications.
