Title (EN) BATTERY UNIT
(FR) UNITÉ DE BATTERIE
(JA) 電池ユニット
Abstract: front page image
(EN)Disclosed is a battery unit (1) comprising a plurality of bipolar cells (2) and collectors (3) arranged between the bipolar cells (2). Each of the bipolar cells (2) is obtained by stacking a plurality of cell elements in each of which a sheet electrode is arranged on both sides of an electrolyte. The collectors (3) serve as heat dissipating members for dissipating the heat generated in the bipolar cells (2). In addition, each of the collectors (3) is provided with a heat dissipating structure which is capable of dissipating the heat generated in the bipolar cells (2).
(FR)L'invention porte sur une unité de batterie (1) comprenant une pluralité de cellules bipolaires (2) et de collecteurs (3) agencés entre les cellules bipolaires (2). Chacune des cellules bipolaires (2) est obtenue par empilement d'une pluralité d'éléments de cellule dans chacun desquels une électrode en feuille est agencée sur les deux côtés d'un électrolyte. Les collecteurs (3) servent d'éléments de dissipation de chaleur pour dissiper la chaleur générée dans les cellules bipolaires (2). De plus, chacun des collecteurs (3) comporte une structure dissipant la chaleur apte à dissiper la chaleur générée dans les cellules bipolaires (2).
(JA) 電池ユニット(1)は、電解質の両側にシート状の電極を有する複数の電池要素を積層した複数のバイポーラ電池(2)と、このバイポーラ電池(2)間に設けられた集電体(3)とを備える。そして集電体(3)を、バイポーラ電池(2)で発生した熱を放散可能な放熱部材として機能させる。また集電体(3)に、バイポーラ電池(2)で発生した熱を放散可能な放熱構造を設ける。
