【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/LLiPF₆/（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LiCoO₂电极的电化学性能。更多还原

【Abstract】 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/LLiPF₆/（EC+DMC+EMC）（1∶1∶1 in a volume ration） can effectively improve the electrochemical performance of MCMB and LiCoO₂ electrodes.更多还原
