Title (EN) ENERGY STORAGE DEVICE
(FR) DISPOSITIF DE STOCKAGE D'ÉNERGIE
Abstract:
(EN) To provide an energy storage device where internal short circuiting of an electrode assembly can be prevented while ensuring easy assembling of the energy storage device. An energy storage device according to an aspect of the present invention includes: an electrode assembly which has an electrode assembly body formed by stacking a positive electrode plate, a separator and a negative electrode plate, and tabs extending from the positive electrode plate and the negative electrode plate; a case formed of a case body which accommodates the electrode assembly therein and a lid plate which closes the case body; an external terminal fixed to the lid plate and electrically connected to the tab; a spacer disposed between the electrode assembly body and the lid plate and having rigidity; and a porous cushion sheet disposed between the spacer and the electrode assembly body having cushioning property, wherein the cushion sheet is welded to the spacer.
(FR) L'invention vise à fournir un dispositif de stockage d'énergie dans lequel un court-circuit interne d'un ensemble d'électrodes peut être empêché tout en assurant un assemblage facile du dispositif de stockage d'énergie. Un dispositif de stockage d'énergie selon un aspect de la présente invention comprend : un ensemble d'électrodes qui a un corps d'ensemble d'électrodes formé par empilement d'une plaque d'électrode positive, d'un séparateur et d'une plaque d'électrode négative, et des pattes s'étendant à partir de la plaque d'électrode positive et de la plaque d'électrode négative ; un boîtier formé d'un corps de boîtier qui reçoit l'ensemble d'électrodes à l'intérieur de celui-ci et d'une plaque de couvercle qui ferme le corps de boîtier ; une borne externe fixée à la plaque de couvercle et connectée électriquement à la patte ; un élément d'espacement disposé entre le corps d'ensemble d'électrodes et la plaque de couvercle et étant rigide ; et une feuille d'amortissement poreuse disposée entre l'élément d'espacement et le corps d'ensemble d'électrodes ayant une propriété d'amortissement, la feuille d'amortissement étant soudée à l'élément d'espacement.
