Title (EN) POWER STORAGE DEVICE
(FR) DISPOSITIF DE STOCKAGE D'ÉNERGIE
(JA) 蓄電デバイス
Abstract:
(EN) A power storage device with high energy density per unit area is provided. This power source device (1) is provided with a first electrode (21), a second electrode (22), and a separator (23). The separator (23) is disposed between the first electrode (21) and the second electrode (22). The separator (23) has a greater surface area than the first and second electrodes (21), (22), and has a nonoverlapping part (23a) that does not overlap with the first and second electrodes (21), (22) in the direction of lamination. The nonoverlapping part (23a) has a corner part or a curved part. A notch or cut is provided in the corner part or curved part. The nonoverlapping part (23a) is folded in the lamination direction.
(FR) L'invention concerne un dispositif de stockage d'énergie ayant une densité d'énergie élevée par unité de surface. Ce dispositif de source d'alimentation (1) est pourvu d'une première électrode (21), d'une seconde électrode (22) et d'un séparateur (23). Le séparateur (23) est disposé entre la première électrode (21) et la seconde électrode (22). Le séparateur (23) possède une plus grande surface par rapport à celle des première et seconde électrodes (21) (22), et comporte une partie sans chevauchement (23a) qui ne chevauche pas les première et seconde électrodes (21) (22) dans la direction de stratification. La partie sans chevauchement (23a) comporte une partie angulaire ou une partie incurvée. Une encoche ou une découpe est prévue dans la partie angulaire ou dans la partie incurvée. La partie sans chevauchement (23a) est pliée dans la direction de stratification.
(JA) 単位面積あたりのエネルギー密度が高い蓄電デバイスを提供する。 蓄電デバイス(1)は、第1の電極(21)と、第2の電極(22)と、セパレータ(23)とを備える。セパレータ(23)は、第1の電極(21)と第2の電極(22)との間に設けられている。セパレータ(23)は、第1及び第2の電極(21),(22)よりも大面積であり、第1及び第2の電極(21),(22)と積層方向に重畳していない非重畳部(23a)を有する。非重畳部(23a)は、角部又は湾曲部を有する。角部又は湾曲部に切欠き又は切り込みが設けられている。非重畳部(23a)が積層方向に沿って折り曲げられている。
