Abstract:
(EN) Provided is an electrolytic solution in which the residual volume does not readily decrease and the resistance increase rate does not readily change, even when the electrolyte solution is stored at high temperature. An electrolytic solution characterized in containing a fluorinated carbonate, a specific additive, and a compound (1) represented by general formula (1): R11CFX11(CH2)n11COOR12 (where R11 is H, F, a C1-C3 non-fluorinated alkyl group, or a C1-C3 fluorinated alkyl group; X11 is H or F; R12 is a C1-C3 non-fluorinated alkyl group or a C1-C3 fluorinated alkyl group; and n11 is an integer from 0 to 3).
(FR) L'invention concerne une solution électrolytique dans laquelle le volume résiduel ne diminue pas facilement et le taux d'augmentation de résistance ne change pas facilement, même lorsque la solution électrolytique est stockée à haute température. L'invention concerne une solution électrolytique caractérisée en ce qu'elle contient un carbonate fluoré, un additif spécifique et un composé (1) représenté par la formule générale (1) : R11CFX11(CH2)n11COOR12 (où R11 est H, F, un groupe alkyle non fluoré en C1-C3, ou un groupe alkyle fluoré en C1-C3; X11 est H ou F; R12 est un groupe alkyle non fluoré en C1-C3 ou un groupe alkyle fluoré en C1-C3; et n11 est un entier allant de 0 à 3).
(JA) 高温で保管した場合でも、残存容量が低下しにくく、抵抗増加率も変化しにくい電解液を提供する。一般式(1):R11CFX11(CHn11COOR12 (式中、R11はH、F、炭素数1~3の非フッ素化アルキル基、又は、炭素数1~3のフッ素化アルキル基、X11はH又はF、R12は炭素数1~3の非フッ素化アルキル基又は炭素数1~3のフッ素化アルキル基、n11は0~3の整数)で示される化合物(1)、フッ素化カーボネート、及び、特定の添加剤を含むことを特徴とする電解液である。
