Abstract:
(EN) The purpose of the present invention is to improve the electrical conductivity of a semisolid electrolyte layer. In order to solve the above-described problem, a semisolid electrolyte layer according to the present invention contains: a semisolid electrolyte that comprises particles and a semisolid electrolyte solution containing a semisolid electrolyte solvent and a low viscosity organic solvent; and a semisolid electrolyte binder. This semisolid electrolyte layer is characterized in that: the semisolid electrolyte solution is supported by the particles; and the ratio of the low viscosity organic solvent to 100% by weight of the mixed solvent of the semisolid electrolyte solvent and the low viscosity organic solvent is 10% by weight or more.
(FR) L'objet de la présente invention est d'améliorer la conductivité électrique d'une couche d’électrolyte semisolide. Afin de résoudre le problème décrit ci-dessus, une couche d'électrolyte semisolide selon la présente invention contient : un électrolyte semisolide qui comprend des particules et une solution électrolytique semisolide contenant un solvant d'électrolyte semisolide et un solvant organique de faible viscosité; et un liant d'électrolyte semisolide. Cette couche d'électrolyte semisolide est caractérisée en ce que : la solution électrolytique semisolide est supportée par les particules; et le rapport du solvant organique de faible viscosité à 100 % en poids du solvant mixte du solvant d'électrolyte semisolide et du solvant organique de faible viscosité est supérieur ou égal à 10 % en poids.
(JA) 半固体電解質層の導電率を向上させることを目的とする。 上記課題を解決するため、本発明に係る半固体電解質層は、粒子、並びに半固体電解質溶媒および低粘度有機溶媒を含む半固体電解液を有する半固体電解質と、半固体電解質バインダとを含む半固体電解質層であって、半固体電解液は、前記粒子に担持され、半固体電解質溶媒および低粘度有機溶媒の混合溶媒100重量%に対する低粘度有機溶媒の比が10重量%以上であることを特徴とする。
