Abstract

La présente invention décrit un électrolyte non aqueux comprenant un sel de lithium, un solvant organique, et un additif. L’additif comprend un premier additif comprenant un composé représenté par une formule particulière et un second additif comprenant du difluorophosphate de lithium. Selon la présente invention, l’électrolyte non aqueux peut former un film stable sur les électrodes, et améliorer ainsi les caractéristiques de stockage et de résistance à haute température d’une batterie secondaire au lithium, ainsi que de l’électrolyte non aqueux.
