Title (EN) POSITIVE ELECTRODE ACTIVE SUBSTANCE LAYER
(FR) COUCHE DE SUBSTANCE ACTIVE D’ÉLECTRODE POSITIVE
(JA) 正極活物質層
Abstract:
(EN) The present invention addresses the issue of providing a positive electrode active substance layer capable of reducing the internal resistance of an all-solid-state lithium ion battery. Provided is a positive electrode active substance layer comprising a positive electrode active substance, a solid-state electrolyte, and a conduction auxiliary agent. The total solid-state electrolyte and conduction auxiliary agent content in the positive electrode active substance layer is 10-40 vol% relative to the total volume of the positive electrode active substance layer. The electron conductivity/lithium ion conductivity ratio is 2-500. The present invention also provides an all-solid-state lithium ion battery using this positive electrode active substance layer.
(FR) La présente invention aborde le problème consistant à pourvoir à une couche de substance active d'électrode positive pouvant réduire la résistance interne d'une batterie au lithium-ion à l'état entièrement solide. L'invention concerne ainsi une couche de substance active d'électrode positive comprenant une substance active d'électrode positive, un électrolyte à l'état solide, et un agent auxiliaire de conduction. La teneur en électrolyte à l'état entièrement solide et en agent auxiliaire de conduction dans la couche de substance active d'électrode positive est située dans la plage allant de 10 à 40 % en volume par rapport au volume total de la couche de substance active d'électrode positive. Le rapport conductivité d'électrons/conductivité du lithium-ion est de 2 à 500. La présente invention concerne également une batterie au lithium-ion à l'état entièrement solide utilisant ladite couche de substance active d'électrode positive.
(JA)  本発明の課題は、全固体リチウムイオン電池の内部抵抗を低減することができる正極活物質層を提供することである。本発明は、正極活物質層であって、正極活物質、固体電解質、及び導電助剤を含有し、正極活物質層における固体電解質及び導電助剤の合計含有量が、正極活物質層の合計体積に対して10体積%~40体積%であり、かつ電子伝導度/リチウムイオン伝導度比が2~500である、正極活物質層を提供する。また、本発明は、この正極活物質層を用いた全固体リチウムイオン電池を提供する。
