Title (EN) NON-AQUEOUS ELECTROLYTE SOLUTION
(FR) SOLUTION D'ÉLECTROLYTE NON AQUEUX
(JA) 非水電解液
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.
(JA)本発明は、(I)フッ素化鎖状スルホン、及び、フッ素化鎖状スルホン酸エステルからなる群より選択される少なくとも1種の化合物、及び、(II)電解質塩を含むことを特徴とする非水電解液である。これにより、フッ酸が発生しても非水電解液の分解が抑制され、二次電池に用いた場合には、電池の膨れや電池性能の低下が起こりにくい非水電解液が提供される。
