Abstract
(EN)
The present invention provides a secondary battery which makes it easy to insert an electrode body and an insulation sheet into a battery container, while preventing the electrode body from moving within the battery container due to external vibration or impact. A secondary battery according to one embodiment of the present disclosure is characterized by being provided with: a plurality of electrode bodies (3) (3x, 3y), each of which comprises a positive electrode plate and a negative electrode plate; an electrolyte solution; an outer case (1) which contains the electrode bodies (3) and the electrolyte solution; and an insulation sheet (14) which is arranged between the electrode bodies (3) and the outer case (1). This secondary battery is also characterized in that: at least one of the electrode bodies (3x, 3y) and the insulation sheet (14) are fixed to each other by the intermediary of an adhesive layer (14a); and the insulation sheet (14) and the outer case (1) are in direct contact with each other without having the adhesive layer (14a) being interposed therebetween, thereby being not fixed to each other by the intermediary of an adhesive layer.

La présente invention concerne une batterie secondaire qui permet d'insérer facilement un corps d'électrode et une feuille d'isolation dans un compartiment de batterie, tout en empêchant le corps d'électrode de se déplacer à l'intérieur du compartiment de batterie en raison d'une vibration ou d'un impact externe. Une batterie secondaire selon un mode de réalisation de la présente invention est caractérisée en ce qu'elle comprend : une pluralité de corps d'électrode (3) (3x, 3y), chacun comprenant une plaque d'électrode positive et une plaque d'électrode négative ; une solution électrolytique ; un boîtier externe (1) qui contient les corps d'électrode (3) et la solution électrolytique ; et une feuille d'isolation (14) qui est disposée entre les corps d'électrode (3) et le boîtier externe (1). Cette batterie secondaire est également caractérisée en ce que : au moins l'un des corps d'électrode (3x, 3y) et la feuille d'isolation (14) sont fixés l'un à l'autre par l'intermédiaire d'une couche adhésive (14a) ; et la feuille d'isolation (14) et le boîtier externe (1) sont en contact direct l'un avec l'autre sans avoir la couche adhésive (14a) interposée entre eux, ainsi n’étant pas fixés l'un à l'autre par l'intermédiaire d'une couche adhésive.
