摘要
研究了2-氯苯甲醚的电化学稳定性及对锂离子电池容量发挥、循环性能和安全性能的影响.2-氯苯甲醚在4.47 V(vs.Li/Li+)处发生氧化反应;添加量为质量分数5%时,以3 C电流充电至10 V,电池安全性很好,且对电池的首次放电容量和循环性能影响很小.
The electrochemical stability of 2 -chloronisole and the effect of 2 -ehloronisole on the performance and safety were studied. 2 - chloronisole can be oxidized at about 4. 47 V ( vs. Li/Li^+ of 5% 2 - chloronisole did not effect the initial discharge capacity and cycle performance of lithium and batteries could keep safe when it was charged to 10 V with a current of 3 C.
