Abstract
(EN) Provided is a bipolar storage battery that, with a simple configuration, can appropriately externally dissipate heat produced in a cell member. A bipolar storage battery (1) comprises: a plurality of cell members (150) which are each provided with a positive electrode (151) that has a positive electrode active material layer (103), a negative electrode (152) that has a negative electrode active material layer (104), and an electrolytic layer (105) that is interposed between the positive electrode (151) and the negative electrode (152); and a plurality of frame units (110), (120), (130) which form a plurality of cells (C) that individually accommodate the plurality of cell members (150). The cell members (150) are electrically connected to each other in series. Formed on an outside surface of at least one of the plurality of frame units (110), (120), (130) is a depression (160) that is open at that outside surface.
(FR) L'invention concerne une batterie de stockage bipolaire qui, avec une configuration simple, peut dissiper de manière appropriée de l'extérieur la chaleur produite dans un élément de cellule. Une batterie de stockage bipolaire (1) comprend : une pluralité d'éléments de cellule (150) qui sont chacune pourvues d'une électrode positive (151) qui a une couche de matériau actif d'électrode positive (103), une électrode négative (152) qui a une couche de matériau actif d'électrode négative (104), et une couche électrolytique (105) qui est interposée entre l'électrode positive (151) et l'électrode négative (152) ; et une pluralité d'unités de cadre (110), (120), (130) qui forment une pluralité de cellules (C) qui reçoivent individuellement la pluralité d'éléments de cellule (150). Les éléments de cellule (150) sont électriquement connectés en série l'un à l'autre. Formée sur une surface extérieure d'au moins l'une de la pluralité d'unités de cadre (110), (120), (130) se trouve une dépression (160) qui est ouverte à cette surface extérieure.
(JA) 簡単な構成によってセル部材で発熱した熱を外部に適切に放熱することができる双極型蓄電池を提供する。双極型蓄電池(1)は、正極用活物質層(103)を有する正極(151)、負極用活物質層(104)を有する負極(152)、および正極(151)と負極(152)との間に介在する電解層(105)を備えた複数のセル部材(150)と、複数のセル部材(150)を個別に収容する複数のセル(C)を形成する、複数のフレームユニット(110),(120),(130)とを備える。セル部材(150)同士は直列に電気的に接続される。複数のフレームユニット(110),(120),(130)のうちの少なくとも1つのフレームユニット(110),(120),(130)の外側面に、外側面に開放する凹部(160)を形成してある。
