Abstract
(EN)
The present invention relates to an electrolyte comprising: a first electrolyte layer facing a negative electrode; and a second electrolyte layer disposed on the first electrolyte layer, wherein the first electrolyte layer has higher ionic conductivity than the second electrolyte layer, and a lithium secondary battery comprising the electrolyte.
(FR)
L'invention concerne un électrolyte comprenant : une première couche d'électrolyte faisant face à une électrode négative; et une seconde couche d'électrolyte disposée sur la première couche d'électrolyte, la première couche d'électrolyte présentant une conductivité ionique supérieure à celle de la seconde couche d'électrolyte. Elle concerne une batterie secondaire au lithium comprenant ledit électrolyte.
