Abstract

Solution électrolyte non aqueuse pour une batterie secondaire au lithium comprenant un sel de lithium et un solvant organique. La solution électrolyte non aqueuse comprend de 0,5 à 5 % en poids de carbonate de vinyléthylène et de 0,1 à 5 % en poids de 1,3-divinyltétraméthyldisiloxane simultanément, par rapport au poids total de la solution électrolyte non aqueuse. Le 1,3-divinyltétraméthyldisiloxane peut résoudre en grande partie l'effet secondaire du gonflement des batteries sans effets de détérioration tels que l'amélioration de la détérioration de la performance et du cycle de vie à la suite de l'ajout de carbonate de vinyléthylène.
