AI Technical Summary
Technical Problem
During the molding process of pouch battery casings, the low residual stretching rate when the punch contacts the pouch can lead to cracks, electrolyte leakage, and reduced insulation resistance.
Method used
The molding method is divided into primary and secondary processes. By using a combination of molds, demolding devices and punches, the protrusions and concave structures are used to disperse the stretching parts and increase the residual rate.
Benefits of technology
It improves the residual rate of the stretched part of the pressed object, prevents cracks in the battery casing and electrolyte leakage, and achieves a deeper molding effect.
