Abstract
(EN)
Provided is a power storage device with superior safety that can detect swelling of the outer cover material at a low cost with a simple constitution. The power storage device (1) comprises a storage element (10), outer cover material (20) that accommodates the storage element (10), and a deformation sensor (30) disposed on an expansion surface (21) of the outer cover material (20). The deformation sensor (30) comprises a sensor film (32) which has a matrix formed from an elastomer or a resin and a conductive filler which is put into that matrix and which bends and deforms with expansion of the outer cover material (20) and at least one pair of electrodes (33a, 33b) connected to the sensor (32). A three-dimensional conductive path is formed in the sensor film (32) by the contact among the pieces of the conductive filler. Electrical resistance increases with the increase in the amount of deformation of the sensor film (32) from a natural state. The storage device (1) detects the swelling of the outer cover material (20) by changes in the electrical resistance that accompany bending and deformation of the sensor film (32).

L'invention porte sur un dispositif de stockage d'énergie ayant une sécurité supérieure, qui peut détecter le gonflement du matériau de boîtier externe à un coût faible et avec une structure simple. Le dispositif de stockage d'énergie (1) comprend un élément de stockage (10), un matériau de boîtier externe (20) qui reçoit l'élément de stockage (10) et un capteur de déformation (30) disposé sur une surface d'expansion (21) du matériau de boîtier externe (20). Le capteur de déformation (30) comprend un film capteur (32) qui a une matrice formée à partir d'un élastomère ou d'une résine et une charge conductrice qui est placée dans cette matrice et qui fléchit et se déforme avec l'expansion du matériau de boîtier externe (20), et au moins une paire d'électrodes (33a, 33b) connectées au film capteur (32). Un trajet conducteur tridimensionnel est formé dans le film capteur (32) par le contact entre les parties de la charge conductrice. La résistance électrique augmente avec l'augmentation de la quantité de déformation du film capteur (32) à partir d'un état naturel. Le dispositif de stockage (1) détecte le gonflement du matériau de boîtier externe (20) par des modifications de la résistance électrique qui accompagne la flexion et la déformation du film capteur (32).
