Title
(EN) SECONDARY BATTERY
(FR) BATTERIE SECONDAIRE
(JA) 二次電池
Abstract
(EN) This secondary battery comprises: a first electrolyte layer including a first electrolyte and a first polymer compound; an electrode and a separator facing each other with the first electrolyte layer interposed therebetween; and a second electrolyte layer that is adjacent to the first electrolyte layer in the direction intersecting the direction in which the electrode and the separator face each other with the first electrolyte layer interposed therebetween, and that contains a second electrolyte and a second polymer compound. The ratio of the second electrolyte weight to the second polymer compound weight is greater than the ratio of the first electrolyte weight to the first polymer compound weight.
(FR) L'invention concerne une batterie secondaire comprenant : une première couche d'électrolyte comprenant un premier électrolyte et un premier composé polymère ; une électrode et un séparateur se faisant face, la première couche d'électrolyte étant interposée entre ceux-ci ; et une seconde couche d'électrolyte qui est adjacente à la première couche d'électrolyte dans la direction croisant la direction dans laquelle l'électrode et le séparateur se font face, la première couche d'électrolyte étant interposée entre ceux-ci, et qui contient un second électrolyte et un second composé polymère. Le rapport du second poids d'électrolyte au second poids de composé polymère est supérieur au rapport du premier poids d'électrolyte au premier poids de composé polymère.
(JA) 二次電池は、第1電解液および第1高分子化合物を含む第1電解質層と、その第1電解質層を介して互いに対向する電極およびセパレータと、その電極およびセパレータが第1電解質層を介して互いに対向する方向と交差する方向において第1電解質層に隣接され、第2電解液および第2高分子化合物を含む第2電解質層とを備える。第2高分子化合物の重量に対する第2電解液の重量の比は、第1高分子化合物の重量に対する第1電解液の重量の比よりも大きい。
