摘要
作为绿色环保能源,锂离子电池已经在电动汽车领域占据了极大的市场份额,并逐步扩大了在军工领域的应用范围,然后电动汽车和军工产品都对锂离子电池的环境适应性提出了更高要求。而处于低温环境的锂离子电池,其放电电压平台和放电容量都会较常温环境有较大幅度的降低。本文分析了锂离子电池在低温条件下性能下降的几种因素,并提出可以从锂盐、溶剂以及添加剂三个方面改善锂离子电池低温电解液的性能。
As clean energies,lithium-ion batteries have already occupied a great market share in the field of electric vehicles and expanded the scope of application in the military fields gradually.While,electric vehicles and military products have higher requirements for the environmental adaptability of lithium-ion batteries.Compared to the ambient temperature,the discharge voltage plateau and discharge capacity of the lithium-ion batteries which in the low temperature environment will reduce obviously.In this paper,several factors that affect the performance of lithium ion batteries at low temperature are analyzed.It is proposed that the performance of low temperature electrolytes for lithium-ion battery can be improved from lithium salts,solvents and additives.
