Abstract: front page image
(EN)Disclosed is a nonaqueous electrolyte solution for lithium secondary batteries wherein an electrolyte salt is dissolved in a nonaqueous solvent. This nonaqueous electrolyte solution is characterized in that a 1,2-cyclohexanediol derivative having a specific structure is contained in the nonaqueous electrolyte solution in an amount of 0.01-30% by weight relative to the nonaqueous electrolyte solution. Also disclosed is a lithium secondary battery using such a nonaqueous electrolyte solution, which is excellent in battery characteristics such as electric capacity, cycle characteristics and storage characteristics and capable of maintaining adequate battery performance for a long time.
(FR)La présente invention concerne une solution électrolytique non aqueuse destinée à des batteries secondaires au lithium, dans laquelle un sel électrolytique est dissous dans un solvant non aqueux. Ladite solution est caractérisée en ce qu’elle contient un dérivé de 1,2-cyclohexanediol ayant une structure spécifique en une quantité de 0,01 à 30 % en poids par rapport à ladite solution. L’invention concerne également une batterie secondaire au lithium utilisant une telle solution, ayant d’excellentes caractéristiques de batterie telles que la capacité électrique, les caractéristiques de cycle et les caractéristiques de stockage et pouvant conserver une performance de batterie adéquate pendant longtemps.
(JA) 本発明は、非水溶媒に電解質塩が溶解されているリチウム二次電池用非水電解液において、該非水電解液中に特定の構造を有する1,2-シクロヘキサンジオール誘導体が、非水電解液に対して、0.01~30重量%含有されていることを特徴とする非水電解液、及びそれを用いたリチウム二次電池であり、電気容量、サイクル特性、保存特性等の電池特性に優れ、かつ長期にわたり電池性能を維持しうる。
