SEALED BATTERY |
| 摘要 |
A sealed battery according to the present invention includes a bottomed cylindrical outer can having an opening, the opening and a sealing plate being crimp-sealed with an insulating gasket interposed therebetween. The sealing plate has a thin portion that serves as a starting point of deformation of the sealing plate when a battery internal pressure increases. When the battery internal pressure increases, the sealing plate is deformed so that a gap is formed between the insulating gasket and the sealing plate and gas in the outer can is vented to the outside of the outer can. The sealing plate may be formed of a single plate-shaped member. |
