Abstract: front page image
(EN)The present invention is a non-aqueous electrolyte solution characterized by containing: (I) at least one compound selected from a group comprising fluorinated chain sulfones and fluorinated chain sulfonic acid esters; and (II) an electrolyte salt. A non-aqueous electrolyte solution is thus provided whereby breakdown thereof is minimized even if hydrofluoric acid is generated, and when used in a secondary battery, said non-aqueous electrolyte solution makes said secondary battery resistant to swelling and performance losses.
(FR)La présente invention concerne une solution d'électrolyte non aqueux caractérisée en ce qu'elle contient : (I) au moins un composé sélectionné dans le groupe comprenant des sulfones à chaîne fluorée et des esters d'acide sulfonique à chaîne fluorée ; et (II) un sel d'électrolyte. Cela conduit à une solution d'électrolyte non aqueux dont la décomposition est minimisée même en cas de dégagement d'acide fluorhydrique et, lors de son utilisation dans une batterie secondaire, ladite solution d'électrolyte non aqueux a pour effet de rendre ladite batterie secondaire résistante au gonflement et à la diminution des performances.
