摘　　要：研究了六甲基二硅氮烷（HMDs）对电解液稳定性和锂离子电池循环性能的影响。加入0．1％的HMDS不会影响电池的首次放电容量，能抑制电解液中LiPF6的水解；常温下以1C在3．0～4．2V循环100次后，电池的容量保持率为92．4％。The effects of hexamethyldisilazane（HMDS）to the stability of electrolyte and cycle performance of Li-ion battery were studied. The addition of 0.1% HMDS did not effect the initial discharge capacity of the battery,could restrain the hydrolysis of LiPF6 in electrolyte,the capacity retention of the battery after 100 cycles with 1 C in 3.0 - 4.2 V was 92.4% at ambient temperature.
