摘　　要：锂离子电池是近年来发展起来的一种新型电池，其研究重点是电池负极材料。根据国内外锂离子电池发展现状，阐述了近年来锂离子电池负极的发展动态，介绍了新型负极材料中的铝、硅、锡、硼基材料以及金属氧化物守金属合金三类，重点介绍了锡基材料，目前研究的重点是提高锂的可逆贮量和减少不可逆容量损失，有利于负极比奎量的提高，从而有利于进一步提高锂离子电池的比能量，提出了新型负极材料存在的问题，并对其应用前景进行了展望。Lithium ion rechargeable battery is a new type of battery developed in recent years. The studies on this system are naturally focused on the anode. Recent development of new negative electrode in foreign countries is reviewed and the current situation of development is introduced in detail. The fin-based, aluminum-based, silicon-based, boron-based materials; metallic oxide; metal alloy as three most important new materials for new cathode materials L-ion batteries are introduced, the tin-based material is introduced in detail. These development is to increase the amount of lithium that can be reversibly stored,and to minimize the irreversibly capacity losses in order to increase further specific capacity of negative electrode and energy density of the battery. In the end, the problem of the new negative electrode,and its application prospect are presentecL
