Abstract:
(EN) Provided is a nonaqueous electrolyte for secondary batteries, which is capable of maintaining high discharge characteristics even at low temperatures. This nonaqueous electrolyte for secondary batteries contains a nonaqueous solvent and a lithium salt that is dissolved in the nonaqueous solvent. The nonaqueous solvent contains a cyclic carbonate, a chain carbonate, a fluoroarene and a carboxylic acid ester; and the cyclic carbonate contains ethylene carbonate. In the nonaqueous solvent, the content of the cyclic carbonate (MCI) is 4.7-90% by mass, the content of the ethylene carbonate (MEC) is 4.7-37% by mass, the content of the chain carbonate (MCH) is 8-80% by mass, the content of the fluoroarene (MFA) is 1-25% by mass, and the content of the carboxylic acid ester (MCAE) is 1-80% by mass.
(FR) La présente invention concerne un électrolyte non aqueux pour batteries secondaires, capable de maintenir des caractéristiques de décharge élevée même pour de basses températures. Cet électrolyte non aqueux pour batteries secondaires contient un solvant non aqueux et un sel de lithium qui est dissous dans le solvant non aqueux. Le solvant non aqueux contient un carbonate cyclique, un carbonate à chaîne, un fluoroarène, et un ester d'acide carboxylique; et le carbonate cyclique contient du carbonate d'éthylène. Dans le solvant non aqueux, la teneur du carbonate cyclique (MCI) est de 4,7 à 90 % en masse, la teneur du carbonate en chaîne (MCH) est de 8 à 80 % en masse, la teneur du fluoroarène (MFA) est de 1 à 25 % en masse, et la teneur de l'ester d'acide carboxylique (MCAE) est de 1 à 80 % en masse.
(JA)  低温でも高い放電特性を維持できる二次電池用非水電解質を提供する。二次電池用非水電解質は、非水溶媒と、前記非水溶媒に溶解したリチウム塩とを含み、前記非水溶媒が、環状カーボネート、鎖状カーボネート、フルオロアレーンおよびカルボン酸エステルを含み、前記環状カーボネートがエチレンカーボネートを含み、前記非水溶媒において、前記環状カーボネートの含有量MCIが4.7~90質量%であり、前記エチレンカーボネートの含有量MECが4.7~37質量%であり、前記鎖状カーボネートの含有量MCHが8~80質量%であり、前記フルオロアレーンの含有量MFAが1~25質量%であり、前記カルボン酸エステルの含有量MCAEが1~80質量%である。
