Document Type and Number:
Japanese Patent JP3178729
Kind Code:
U
Abstract:
A power storage device (20) is provided with an upper cover (201), a cell module (202) and a lower cover (203). A tab (2022) is locally formed at each of two sides of the cell module (202). When welded with an electrical connection part (2023) of an electrode (204), the tab (2022) merely needs to be placed horizontally or be slightly at an inclination angle, and one-time bending is performed. Therefore cracks to a plasticized metal protective film wrapped on the outer edge of the tab or to the tab itself are limited because multiple bending is avoided.
