Laser welding defects detection in lithium-ion battery poles
Despite the fact that LSW is capable to weld a large number of battery poles on a battery plate quickly, its products are often defective due to complex parameter configurations. In the situation when the laser pulse energy is high, it can lead to ''weldingholes'', ''continuousholes'', and ''burn'' defects.

CHAPTER 3 LITHIUM-ION BATTERIES
A Li-ion battery is composed of the active materials (negative electrode/positive electrode), the electrolyte, and the separator, which acts as a barrier between the negative electrode and positive electrode to avoid short circuits. The active materials in Liion cells are the components that - participate in the oxidation and reduction reactions.
