Battery pole piece spot welder use of ultrasonic metal welding principle, ultrasonic metal welding should be classified as don't need preheating welding. Oxidation surface is the great friction welding which division, and at the same time two parts are pressed together.

Batteries achieve the desired operating voltage by connecting several cells in series; each cell adds its voltage potential to derive at the total terminal voltage. Some packs may consist of a combination of series and parallel connections.…

Imagine having access to a battery, which has the potential to power your phone for five continuous days, or enable an electric vehicle to drive more than 1000km without needing to “refuel.” Monash University researchers are on the brink…
