Title
(EN) NON-AQUEOUS ELECTROLYTE AND ELECTROCHEMICAL DEVICE WITH AN IMPROVED SAFETY
(FR) ÉLECTROLYTE NON AQUEUX ET DISPOSITIF ÉLECTROCHIMIQUE PRÉSENTANT UNE SÉCURITÉ AMÉLIORÉE
Abstract
(EN)
Disclosed are a non-aqueous electrolyte comprising a lithium salt and a solvent, the electrolyte containing, based on the weight of the electrolyte, 1-10 wt% of a compound of Formula (1) or its decomposition product, and 1-10 wt% of an aliphatic di-nitrile compound, as well as an electrochemical device comprising the non-aqueous electrolyte. Also disclosed is an electrochemical device comprising: a cathode having a complex formed between a surface of a cathode active material and an aliphatic di-nitrile compound; and a non-aqueous electrolyte containing 1-10 wt% of a compound of Formula (1) or its decomposition product based on the weight of the electrolyte.

L'invention concerne un électrolyte non aqueux comprenant un sel de lithium et un solvant, l'électrolyte contenant, en fonction du poids de l'électrolyte, entre 1 et 10% en poids d'un composé représenté par la formule (1) ou de son produit de décomposition, et entre 1 et 10% en poids d'un composé dinitrile aliphatique, ainsi qu'un dispositif électrochimique comprenant l'électrolyte non aqueux. L'invention concerne également un dispositif électrochimique comprenant: une cathode présentant un complexe formé entre une surface d'un matériau actif de cathode et un composé dinitrile aliphatique; et un électrolyte non aqueux contenant entre 1 et 10% en poids d'un composé représenté par la formule (1) ou de son produit de décomposition en fonction du poids de l'électrolyte.
