摘　　要：锂离子电池性能易受温度影响,在低温下,容量衰减大,性能受到影响甚至无法使用,限制了其广泛应用。电解液是电池的重要组成,其性能决定了低温电池性能的优劣。因此低温电解液的研究引起了广泛关注并取得了重要进展。综述了近来国内外研究人员在低温电解液溶剂、锂盐与添加剂等方面的优化进展,并对今后低温电解液的发展方向进行了展望。The performance of U-ion battery is highly affected by temperature, and especially at low temperature, large capacity attenuation happens and the performance of battery is significantly influenced, and even the battery can＇t be used, which limits its wide application. Electrolyte is an important part of LIB and its performance directly determines the merits and defects of low temperature battery performance. Therefore, the research of low temperature electrolytes has attracted wide attentions of scientists, and important progress has been made. The optimization progress on solvents, lithium salts and additives of low temperature electrolytes made by researchers at home and broad was reviewed. Simultaneously, the development trends of low temperature electrolyte for Li-ion battery were predicted.
