Sealed prismatic storage battery |
摘要 |
A sealed and prismatic storage battery characterized by such features as a high volumetric energy density, high compressivity and the like is provided. A battery case has an inner surface and an outer surface of each respective corner section formed of a curvature. The thickness of the corner section is 2.5 mm, a radius of curvature of the outer surface is 5.0 mm, a radius of curvature of the inner surface is 2.5 mm, and a thickness of a small thickness section between the corner section and the flat plane section is 2.0 mm. The position of the thinnest wall section coincides with a position where the radius of a circular arc forming the inner surface of the corner section crosses perpendicularly the outer side surface of the battery case.
