低温锂离子电池研究现状及发展前景

Research on low temperature performance of lithium-ion battery

锂离子电池工作温度一般在-20-60℃范围内，而在低温条件下对锂电池具有更高的要求。目前，我国对锂离子电池低温性能的研究较少，难以满足锂电池在低温条件下的使用要求。从电解液、负极材料以及导电剂三方面对锂离子电池低温性能进行系统的分析和总结。并对未来的研究方向和应用前景进行展望。

The working temperature of lithium-ion battery is generally at the range of --20-60 ~C, while at low temperature, it will have a higher requirements for lithium-ion battery. At present, the low temperature performance of lithium-ion battery has few studies in our country; it is difficult to meet the using requirements of lithium-ion battery under the condition of low temperature. The approaches of improving low temperature performance of lithium-ion battery were discussed in this article by electrolyte, cathode material and conductive additives. The development and application trend of low temperature performance for lithium-ion battery was also discussed.
