【摘要】 以标题化合物为锂离子电池电解液添加剂,提高了锂离子电池电解液在贮存和高温条件下的色度稳定性。通过测定不同亚磷酸三苯酯添加量下电解液的色度及电导率,得出亚磷酸三苯酯的最佳添加量为0.2%。电化学测试结果表明,亚磷酸三苯酯的添加不影响锂离子电池的充放电及循环性能。更多还原

【Abstract】 Triphenyl phosphite as a stability additive in electrolyte for lithium-ion battery can improve the color stability of electrolyte at high temperature.The conductivity of electrolyte and electrochemical performance of lithium-ion batteries were studied.The results showed that the optimal content of triphenyl phosphite was 0.2%(by weight).Meanwhile,triphenyl phosphite does not affect the charge-discharge and cycle performances of lithium-ion battery electrolyte.更多还原
