Shaping processing method for arc-shaped battery, and arc-shaped battery

The invention provides a shaping processing method for an arc-shaped battery, and the arc-shaped battery. The shaping processing method for the arc-shaped battery comprises the following steps: carrying out pre-pressing operation on a battery cell so as to allow the battery cell to form an arc-shaped battery cell; providing a shaped battery cell; connecting the shaped battery cell with the arc-shaped battery cell; performing stamping operation on an aluminum-plastic film sheet body so as to allow an arc-shaped accommodating groove matched with the arc-shaped battery cell to be formed in the aluminum-plastic film sheet body; placing the shaped battery cell and the arc-shaped battery cell which are connected with each other in the arc-shaped accommodating groove; and bending the aluminum-plastic film sheet body to allow the aluminum-plastic film sheet body to form an arc-shaped packaging sleeve covering the shaped battery cell and the arc-shaped battery cell. According to the invention, the ...
