摘　　要：综述了锂离子电池适用于宽温度范围电解液的研究现状和发展前景。总结了前人在新型锂盐的开发和研究、溶剂体系的改善、添加剂的引入等方面做出的努力,提出了从寻找能替代Li PF6的锂盐以提高电池的高温性能,研究新的溶剂组合和新型低熔点溶剂以提升电池的低温性能,再结合其他添加剂改善电解液与电极界面性能来拓宽锂离子电池应用的温度范围的研究思路。Research progress and prospects of wide operating temperature rang electrolyte for li-ion batteries were summarized. Others were making efforts on developing new lithium salts, improving solvent system and finding new additives. Finding lithium salt that could replace Li PF6 to improve the high temperature performance. Research on low melting point solvent was made to improve the low temperature performance and getting additives to modify the interface between electrode and electrolyte, so as to get a type of electrolyte that could operated at wide temperature range.
