When talking about EV vehicles it is indispensable to talk about li-ion battery and more specifically, about the cells that compose them, as high quality battery cells are not only a key component of battery modules and packs, but are able to provide better conductivity and efficiency, resulting in better EV performance.
Battery cells used in EV manufacturing come in three typical formats: cylindrical, prismatic and pouch. Li-ion cell batteries, regardless of their format, are composed by a cover, a case, a positive terminal, a negative tab, a cathode (positive plate), an anode (negative plate) and a separator.
Fiber laser makes the whole li-ion battery cell manufacturing process easier and better, as it provides ready solutions for all common battery cell applications, from foil cutting and drying to welding all the different components of the battery.
Here we present how fiber laser solutions deliver better results in the manufacture of li-ion batteries. These include high-power pulsed lasers and diode laser arrays for electrode processing, and adjustable mode beam (AMB) lasers for low porosity metal welding.
