摘要
研究了LiPF6、双草酸硼酸锂(LiBOB)及它们的混合物在乙烯碳酸酯(EC)+碳酸甲乙酯(EMC)+碳酸二甲酯(DMC)(体积比1∶1∶1)中的电化学性能。LiPF6-LiBOB电解液与LiPF6电解液相比,提高了金属锂的循环效率,电池的平均电压、大电流放电能力及高温性能;与LiBOB电解液相比,提高了溶液的电导率、电池的室温放电比容量及低温性能。
The electrochemieal performance of LiPF6 ,lithium bisoxalateborate (LiBOB) and their mixture in ethylene carbonate (EC) + ethyl methyl carbonate (EMC) + dimethyl carbonate (DMC) (vol, 1:1 : 1) was studied. Compared with LiPF6 electrolyte, the LiPF6-LiBOB electrolyte improved the cycle efficiency of metal lithium, the average voltage, heavy load discharge performance and high temperature performance of the battery;compared with LiBOB electrolyte, it improved the conductivity of solution, at room temperature specific discharge capacity and low temperature performance of the battery.
