description The invention relates to a lithium ion battery electrolyte and a lithium ion battery using the same. In order to solve the problems of poor cycle performance and low safety performance of the existing lithium battery under high voltage, the invention provides the lithium ion battery electrolyte, the lithium ion battery electrolyte comprises a lithium salt, an additive and a non-aqueous organic solvent, the lithium salt is lithium hexafluorophosphate and/or lithium bis (fluorosulfonyl) imide, the additive comprises a tripyridyl phosphate compound, and the non-aqueous organic solvent is a non-aqueous organic solvent. Based on the combination of the tripyridyl phosphite compound and the lithium salt, the cycle performance, the overcharge capacity and the high-temperature storage performance of the high-voltage battery are obviously improved at the same time. 本发明涉及一种锂离子电池电解液及使用该电解液的锂离子电池。为了解决现有锂电池存在高电压下循环性能不好以及安全性能不高的问题，本发明提供一种锂离子电池电解液，其包括锂盐、添加剂和非水有机溶剂，锂盐为六氟磷酸锂和/或双氟磺酰亚胺锂，添加剂包括三吡啶基磷酸酯化合物，基于三吡啶基亚磷酸酯化合物和锂盐的组合，高电压电池的
