The selection and use of wires are very critical in the manufacture of lithium batteries. Currently, one of the most commonly used welding methods is done by laser welding.

Method:
Use laser to corrugate the two ends of the wire first, then pre-drill holes on the electrode sheet, pass the wire handle through the hole, and finally weld the wire and the electrode sheet together with a laser.

Precautions:
- Select the appropriate wire diameter and material. When selecting a wire, it is necessary to consider its conductivity and whether it meets the requirements of lithium battery manufacturing.
-The laser temperature should be adjusted according to the wire material. Wires of different materials have different soldering temperatures, which need to be adjusted according to specific conditions.
- The laser welding time should not be too long to avoid deformation of the wire and weaken the mechanical strength.
