Abstract

La présente invention concerne un dispositif de stockage électrique. Dans ledit dispositif de stockage électrique, des effets suffisants de dissipation thermique peuvent être obtenus sans devoir augmenter les tailles plus que nécessaire. Dans le dispositif de stockage électrique (10), une pluralité de cellules de stockage électrique en forme de plaque plate (20, 20) sont empilées dans un boîtier extérieur (11). Chaque cellule de stockage électrique (20) se trouve entre une paire composée d'une première plaque de dissipation thermique (31) et d'une seconde plaque de dissipation thermique (32), qui sont plus grandes que la cellule de stockage électrique (20). Sur la surface intérieure du boîtier extérieur (11), une section de rainure profonde (17) et une section de rainure peu profonde (16) dans lesquelles sont insérées respectivement la première plaque de dissipation thermique (31) et la seconde plaque de dissipation thermique (32) sont formées. Dans la section de rainure profonde (17) et la section de rainure peu profonde (16), un matériau de résine (19) qui possède une conductivité thermique est appliqué entre les première et seconde plaques de dissipation thermique (31, 32) et le boîtier extérieur (11).
