摘要
在电解液中加入适量的添加剂,是改善锂离子电池性能的一种有效方法。研究了4-甲基亚硫酸乙烯酯(4-MDO)对锂离子电池性能的影响,结果表明,在1.0 mol/LLiPF_6/(EC+DMC+EMC)(体积比为1∶1∶1)电解液中添加质量分数为0.3%的4-MDO,可以有效改善MCMB和LiCoO_2电极的电化学性能。
The appropriate addition of additives in the electrolyte is one of valid methods to improve the properties of lithium ion batteries. The effects of 4-methyl-1,3,2-dioxathiolane-2-oxide(4-MDO) on the properties of lithium ion batteries were investigated. The results show that the addition of 0.3%(by weight) 4-MDO in 1.0 mol/LLiPF_6/(EC+DMC+EMC)(1∶1∶1 in a volume ration) can effectively improve the electrochemical performance of MCMB and LiCoO_2 electrodes.
