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
