[0028] Furthermore, the first component glass is provided with three glass chamfer shapes, namely, a 90° concave chamfer, a 45° oblique angle, and a 90° rounded angle, and the chamfer directions are all located at the four corners of the rectangular glass.
[0029] Furthermore, the second component glass is designed with a groove structure in the central area of the short side of the glass, and a semicircular groove and a regular quadrilateral groove structure are provided.
[0030] Furthermore, the third component glass adds a short-side edge groove structure on the second component glass, and increases the number of grooves and hole structures.

The power generation area of the battery cell is placed in the center of the glass. Compared with the power generation area of the conventional laminate, the edge blank area is larger and more.
