Laser plastic welding is a new type of welding technology, the principle of which is to locally heat the plastic material through the laser beam, make it melt, and then cool it to form a weld. Laser plastic welding technology has the advantages of fast welding speed, high welding strength and small welding deformation.

In the energy storage battery manufacturing, laser plastic welding is mainly used for battery shell, battery diaphragm and battery pole welding. Battery shell welding can improve the sealing and strength of the shell; battery diaphragm welding can improve the stability and durability of the diaphragm; battery pole welding can improve the conductivity and firmness of the pole.
