Here are some of the popularly used welding and bonding techniques in battery manufacturing today: Spot welding/resistance welding; Ultrasonic welding; Laser welding; Wire bonding; Tab bonding; Spot welding:
This welding process is used primarily for welding two or more metal sheets, in case of battery it is generally a nickel strip and positive terminal/negative terminal of the battery together by applying pressure and heat from an electric current to the weld area. Advantages: Low initial costs.
Can be used to weld critical parts like battery tabs and foils. Challenges faced by using laser welding: Wire bonding is well matured technology which was invented for the semiconductor industry and standard technology for semiconductor chips since 1970s, and also Tesla and ola electric batteries are wire bonded.
Whether to power our latest portable electronic device, power tool, or hybrid/electric vehicle, the removable battery pack is essential to our everyday lives. Tab-to-terminal connection is one of the key battery pack welding applications.
