Abstract

La présente invention décrit une batterie secondaire au lithium avec une électrode négative, une électrode positive positionnée à l’opposé de l’électrode négative, un séparateur disposé entre l’électrode négative et l’électrode positive, et un électrolyte non aqueux dont l’électrode négative comprend un matériau actif à base de silicium. Le matériau actif à base de silicium comprend un composé représenté par SiOx, où 0 x<2. L’électrolyte non aqueux comprend un sel de lithium, un solvant organique et un additif. L’additif comprend un premier additif et un deuxième. Le premier additif comprend un composé à base de coumarine représenté par une formule particulière. Le deuxième additif comprend au moins un borate fluoromalonato(difluoro) de lithium (LiFMDFB), un borate difluoro(oxalato) de lithium (LiDFOB), du difluorophosphate de lithium (LiDFP), ou du phosphate difluorobis-(oxalate) de lithium(LiDFOP).
