The requirements of energy storage and battery life for battery application are higher and higher in the market, and the requirements of battery weight and cost are getting lower and lower. Cost effective, high performance batteries in power and alternative energy Industry application is very attractive. Batteries usually contain a lot of Materials such as zinc, steel, aluminum, copper, titanium, nickel, etc. these metals may be made into electrodes, wires, or enclosures based on weight and cost minimization Considering that they should be as thin as possible, the conductivity, strength, air tightness, metal fatigue and corrosion resistance of each battery are typical welding quality assessment Price standard.
Laser welding has always been an indispensable process in the lithium battery manufacturing process. A large number of materials have been applied to laser welding, such as stainless steel shell, aluminum shell, polymer, etc. The unique high speed of laser welding is unmatched by other welding technologies. With the continuous development of the industry, higher requirements are put forward for the efficiency and quality of laser welding. Fiber laser promotes high-speed welding, which can realize low heat input and high solidification speed at the weld joint, and can effectively control the occurrence of mixing Solidification defects in metal welding.
