Abstract:
(EN) The present invention addresses the problem of providing a layered electrode body and a power storage element that are able to effectively suppress electrodeposition. The layered electrode body according to one embodiment of the present invention is provided with: a positive electrode plate having a tab protruding from a first edge; at least one pair of separators which have a resin layer and a heat resistant layer formed on the resin layer, and which cover first and second surfaces of the positive electrode plate in a state in which the heat resistant layer faces the positive electrode plate; and a negative electrode plate which is disposed so as to face the positive electrode plate across the separator, wherein an outer peripheral side of the positive electrode plate has a plurality of welding regions where the at least one pair of separators are welded together; and the plurality of welding regions include a first welding region which extends intermittently and approximately parallel to the first edge of the positive electrode plate, and a second welding region which extends continuously and approximately perpendicular to the first edge.
(FR) La présente invention aborde le problème de la fourniture d'un corps d'électrode en couches et d'un élément de stockage d'énergie qui sont capables d’empêcher efficacement l'électrodéposition. Le corps d'électrode en couches selon un mode de réalisation de la présente invention comporte : une plaque d'électrode positive ayant une languette faisant saillie à partir d'un premier bord; au moins une paire de séparateurs qui ont une couche de résine et une couche résistante à la chaleur formée sur la couche de résine, et qui couvrent des première et seconde surfaces de la plaque d'électrode positive dans un état dans lequel la couche résistante à la chaleur fait face à la plaque d'électrode positive; et une plaque d'électrode négative qui est disposée de manière à faire face à la plaque d'électrode positive à travers le séparateur, un côté périphérique externe de la plaque d'électrode positive ayant une pluralité de régions de soudage, l'au moins une paire de séparateurs étant soudées l'une à l'autre; et la pluralité de régions de soudage comprennent une première région de soudage qui s'étend de façon intermittente et approximativement parallèle au premier bord de la plaque d'électrode positive, et une seconde région de soudage qui s'étend de façon continue et approximativement perpendiculaire au premier bord.
(JA) 本発明は、効果的に電析を抑制できる積層電極体及び蓄電素子を提供することを課題とする。本発明の一態様に係る積層電極体は、第一辺から突出するタブを有する正極板と、樹脂層と前記樹脂層上に形成された耐熱層とを有し、前記耐熱層を前記正極板に対向させた状態で前記正極板の第一面及び第二面を覆う少なくとも一対のセパレータと、前記セパレータを介して前記正極板に対向する負極板とを備え、前記正極板の外周側に前記少なくとも一対のセパレータが互いに溶着された複数の溶着領域を有し、前記複数の溶着領域が、前記正極板の第一辺と略平行かつ間欠的に延びる第一溶着領域と、前記第一辺と略垂直かつ連続的に延びる第二溶着領域とを含む。
