摘要 为了提高锂离子电池的安全性,合成了阻燃剂三氟乙氧基磷酸酯(TFP),讨论了TFP含量对1.0 mol/L LiPF6/EC+DMC(体积比1∶1)电解液的可燃性和电化学性能的影响。结果表明:电解液的可燃性和电导率随着TFP含量的增大而降低;当TFP含量大于8.0%时,电解液不可燃。TFP含量为10.0%时,电解液的电导率由10.21 mS/cm(不含TFP)降至8.79 mS/cm(20℃);添加TFP对电解液的分解电压没有影响。当TFP含量为5.0%和10.0%时,Li/LiCoO2半电池的最高放电容量由126 mAh/g(不含TFP)分别增加到145 mAh/g和129 mAh/g。 In order to improve the safety performance of Li-ion battery, tris(2,2,2-trifluoroethoxyl) phosphate ( T FP) flame retardant was synthesized. The effects of the TFP content on the flammability and electrochemical performance of 1.0 mol/L LiPF6/EC + DMC (1 : 1, V/V) electrolyte were discussed. The results showed that the flammability and the conductivity of the electrolyte decreased with the increasing of the TFP content. When the TFP content was above 8.0%, the electrolyte was nonflammable. When the TFP content was 10.0%, the conductivity of the electrolyte decreased from 10.21 mS/cm (no TFP) to 8.79 mS/cm(20 ℃). The decomposition voltage of the electrolyte was not effected by adding TFP. The maximal discharge capacity of Li/LiCoO2 half cell increased from 126 mAh/g (no TFP) to 145 mAh/g and 129 mAh/g when the TFP content was 5.0% and 10.0% ,respectively.
