Abstract:
The present application relates to a battery cell and an electronic device. The battery cell according to an embodiment comprises: an electrode assembly, including an electrode plate; and a shell, receiving the electrode assembly and including a first edge seal, a second edge seal and a circular edge seal connecting the first edge seal and the second edge seal, wherein the circular edge seal defines a virtual circular arc region with a radius R and a radian angle Ø, wherein the electrode plate has a first edge, a second edge, and a third edge connecting the first edge and the second edge, and a virtual extension line of the first edge and a virtual extension line of the second edge intersect to form a virtual intersection point A; a point on the third edge has a minimum distance L relative to the virtual intersection point A; and the virtual extension lines of the first edge and the second edge form a corner at the virtual intersection point A toward the third edge, and an angle of the corner is greater than 0 degrees and less than 180 degrees. The battery cell and the electronic device provided by the present application have higher safety performance, a higher space utilization ratio and a higher energy density.
