Abstract:
(EN) Provided are: a separator for batteries, which suppresses increase of the internal resistance and decrease of the cycle performance, and which is suitable for improving the yield of a battery production process; an electrode laminate which is provided with this separator for batteries; an electrode roll; and a battery. A separator for batteries, which comprises a film that contains a swellable resin, and wherein the swelling starting temperature T0 is from 30°C to 78°C (inclusive) and the maximum swelling stress Fpeak is 5 cN or more.
(FR) L'invention concerne : un séparateur pour batteries, qui supprime l'augmentation de la résistance interne et la diminution des performances de cycle, et qui est approprié pour améliorer le rendement d'un processus de production de batterie; un stratifié d'électrode qui comprend ce séparateur pour des batteries; un rouleau d'électrode; et une batterie. Un séparateur pour batteries, qui comprend un film qui contient une résine gonflable, et dans lequel la température de départ de gonflement T0 est de 30 °C à 78 °C (inclus) et la contrainte de gonflement maximale Fpic est d'au minimum 5 cN.
(JA) 内部抵抗の増加及びサイクル性能の低下を抑制し、電池製造工程における歩留り改善をするに適した電池用セパレータ、該電池用セパレータを備える電極積層体、電極巻回体、及び電池を提供する。膨潤性樹脂を含む膜を有し、膨潤開始温度T0が30℃以上78℃以下であり、膨潤最大応力Fpeakが5cN以上である電池用セパレータ。
