摘要：【中文】本发明公开了一种锂离子电池电解液，包括锂盐、添加剂和非水性有机溶剂，按在锂离子电池电解液中的质量百分含量，所述添加剂组成为：成膜型添加剂1.5‑3.0％，磷酸酯添加剂0.5‑2.0％，具有三氟化硼烃基硫酸锂结构的化合物0.5‑2.0％。本发明还提供含有上述锂离子电池电解液的锂离子电池。本发明通过将三类添加剂的有机组合可以实现在高电压或高镍体系中具有较好的常温和高温循环稳定性，同时电池的阻抗较低，可以实现高低温性能的兼顾。 【EN】The invention discloses a lithium ion battery electrolyte, which comprises lithium salt, an additive and a non-aqueous organic solvent, wherein the additive comprises the following components in percentage by mass in the lithium ion battery electrolyte: 1.5-3.0% of film-forming additive, 0.5-2.0% of phosphate additive and 0.5-2.0% of compound with boron trifluoride hydrocarbyl lithium sulfate structure. The invention also provides a lithium ion battery containing the lithium ion battery electrolyte. According to the invention, the organic combination of the three additives can realize better normal temperature and high temperature cycling stability in a high voltage or high nickel system, and simultaneously, the impedance of the battery is lower, so that the compatibility of high and low temperature performance can be realized.
