Title (EN) ELECTROLYTE SOLUTION FOR LITHIUM ION BATTERY, AND BATTERY
(FR) SOLUTION ÉLECTROLYTIQUE POUR BATTERIE AU LITHIUM-ION, ET BATTERIE
(ZH) 一种锂离子电池电解液及电池
Abstract:
(EN) Provided is an electrolyte solution, comprising a lithium salt, an additive and an organic solvent, wherein the additive is poly(ethylene glycol)-poly(propylene glycol)-poly(ethylene glycol). Also provided is a battery, wherein same uses the electrolyte solution provided in the present invention. The electrolyte solution and the battery provided in the present invention can effectively control a thermal runaway phenomenon that may occur in the process of using the battery, and at the same time, there is little negative influence on the battery itself.
(FR) La présente invention concerne une solution électrolytique, comprenant un sel de lithium, un additif et un solvant organique, l'additif étant du poly(éthylène glycol)-poly(propylène glycol)-poly(éthylène glycol). L'invention concerne également une batterie utilisant ladite solution électrolytique. La solution électrolytique et la batterie selon la présente invention peuvent commander efficacement un phénomène d'emballement thermique qui peut se produire pendant l'utilisation de la batterie tout en ayant une influence négative limitée sur la batterie elle-même.
(ZH) 本发明提供了一种电解液,包括锂盐、添加剂和有机溶剂,其中,所述添加剂为聚乙二醇-聚丙二醇-聚乙二醇。本发明还提供了一种电池,该电池使用本发明提供的电解液。本发明提供的电解液和电池,能够有效控制电池使用过程中可能出现的热失控现象,并且同时对电池本身性能的负面影响很小。
