| 摘 要： | 选用恒流充放电法测试了EC、DEC、DMC和EMC等有机溶剂体系对锂离子电池的容量保持率、平台保持率、充放电循环性能和温度特性的影响.实验结果表明:二乙基碳酸酯(DMC)不但具有较高的平台保持率,而且有利于电池的大电流充放电;二甲基碳酸酯(DEC)对电池的循环寿命有较大的改善作用;乙基甲基碳酸酯(EMC)具有较好的温度特性.

| Abstract: | The influences of organic solvents ethylene carbonate (EC),diethyl carbonate(DEC),dimethyl carbonate(DMC) and ethyl methyl carbonate(EMC) in various combination on the capacity holding rate,plateau holding rate,charge-discharge perfor-mance and temperature properties of Li-ion batteries were investigated by galvanostatic charge-discharge. The experimental results indicated that DMC had higher plateau holding rate,in favor of charging-discharging properties at higher current density.DEC could improve cycle life of Li-ion battery and EMC had better temperature properties. |
