Abstract:
(EN) A non-aqueous electrolyte including: (I) at least one type selected from the group consisting of oxalate salt, difluorophosphate, an ionic complex having a cyclic structure, an imide anion-containing salt, a Si-containing compound, a sulfuric ester compound, an organophosphate compound, a cyclic carbonate compound, an isocyanate compound, a cyclic acetal compound, a cyclic acid anhydride, a cyclic phosphazene compound, and an aromatic compound; (II) a monomer indicated by general formula [1]; (III) a non-aqueous organic solvent; (IV) a solute; and (V) an additive for a non-aqueous electrolyte, being an oligomer having a repeating unit indicated by general formula [2] and having a number-average molecular weight in polystyrene terms of 170-5,000. The (V) content relative to a total content of 100% by mass of (I), (II), (III), (IV), and (V) is 0.03%-14.0% by mass. Formula [1]: [In formula [1], R indicates a hydrogen atom, halogen, or a lower alkyl group. R may be all the same or different and may join and form a cyclic structure.] Formula [2]: [In formula [2], the bracket contents indicate the repeating unit. R indicates a hydrogen atom, halogen, or a lower alkyl group. R may all be the same or different and may join and form a cyclic structure.]
(FR) La présente invention concerne un électrolyte non aqueux qui comprend : (I) au moins un type choisi dans le groupe constitué par du sel d'oxalate, du difluorophosphate, un complexe ionique doté d'une structure cyclique, un sel comportant un anion imide, un composé comportant du Si, un composé d'ester sulfurique, un composé organophosphaté, un composé carbonate cyclique, un composé isocyanate, un composé acétal cyclique, un anhydride d'acide cyclique, un composé phosphazène cyclique et un composé aromatique ; (II) un monomère représenté par la formule générale [1] ; (III) un solvant organique non aqueux ; (IV) un soluté ; et (V) un additif destiné à un électrolyte non aqueux, qui est un oligomère doté d'une unité de répétition représentée par la formule générale [2] et doté d'un poids moléculaire moyen en nombre en termes de polystyrène se situant entre 170 et 5000. La teneur (V) par rapport à une teneur totale de 100 % en masse de (I), (II), (III), (IV) et (V) se situant entre 0,03% et 19,0% en masse. Formule [1] : [Dans la formule [1], R représente un atome d'hydrogène, un halogène, ou un groupe alkyle inférieur. R peuvent être tous identiques ou différents et peuvent se rejoindre et former une structure cyclique.]Formule [2] : [Dans la formule [2], les contenus entre crochets représentent l'unité de répétition. R représente un atome d'hydrogène, un halogène, ou un groupe alkyle inférieur. R peuvent tous être identiques ou différents et peuvent se rejoindre et former une structure cyclique.]
