Abstract: front page image
(EN)Provided is a secondary battery with which ignition and explosion caused by short circuiting can be inhibited. This secondary battery (10) is provided with a battery element (4) which is at least partially surrounded by a stretchable sheet (11) having a surface resistivity in the range of 10-2 to 1010 Ω/sq, which is accommodated in a container (5) along with an electrolyte, and in which positive electrodes (1) and negative electrodes (2) are stacked or wound with separators (3) therebetween.
(FR)L'invention concerne un accumulateur qui permet d'inhiber l'inflammation et l'explosion causées par les courts-circuits. L'accumulateur (10) comporte un élément de batterie (4) qui est entouré au moins partiellement d'une feuille étirable (11) dont la résistivité de surface est comprise entre 10-2 et 1010 Ω/sq, lequel est logé dans un récipient (5) contenant également un électrolyte, et dans lequel des électrodes positives (1) et des électrodes négatives (2) sont empilées ou enroulées avec des séparateurs (3) entre elles.
(JA) 短絡による破裂や発火を防止することができる二次電池を提供する。本発明の二次電池10は、表面抵抗率が10-2Ω/sq~1010Ω/sqの伸長性を有する伸長性シート11によって少なくとも一部が囲まれており、電解液とともに容器5に収容された、正極電極1と負極電極2とがセパレータ3を介して積層または巻回した電池要素4を有する。
