Title:
フィルム外装電気デバイス
Document Type and Number:
Japanese Patent JP5835433
Kind Code:
B2
Abstract:
A battery element (2) includes a positive electrode and a negative electrode stacked via a separator. A collector portion (3) is formed by collectively bonding each of positive electrode plates and negative electrode plates which extend outward from this stacked region. Laminated films (5, 6) are obtained by laminating a thermally-fusible resin layer and a metal layer, and by sealing the battery element (2) and electrolyte by thermally fusing sealing portion (8) at a peripheral edge. A tab (4) is connected to collector portion (3) and extends outward from the laminated films (5, 6). An overlaying member (7) includes a protective region (7d) which protects the laminated films (5, 6) from corners (2c) of the battery element (2), corners (3c) of the collector portion (3) and corners (4c) of the tab (4), and a communication portion (7c) through which electrolyte can pass.
