【Abstract】 The status and development of R&D of the negative electrode materials in Li-ion battery was discussed. Up to now, the applicable negative electrode materials for Li-ion battery were basically carbon. The capacity was higher than 300mAh/g and approached the theoretical specific capacity of LiC 6(372mAh/g).The future emphasis of the R&D of the materials would be higher capacity, higher charge/discharge efficiency,higher cyclic performance and lower cost.The specific capacity of a practical negative electrode material would be over the theoretical level of LiC 6.更多还原
