A lithium battery welding machine (also called a spot welder) uses resistance welding to join lithium battery cells and terminals. It works by passing a current through the contact points, generating heat that melts solder to form a strong connection. Welding Device: This core component includes the welding head, electrodes, and control system.
Common battery welding technologys are: ultrasonic welding, resistance spot welding, laser welding, pulse TIG welding. This post combines the application results of the above battery welding technologies in lithium-ion battery systems, and explores the influencing factors. Ultrasonic welding is a solid state battery welding process.
Tabs and Busbars: These are tiny metal strips that join the different battery cells in a pack together. Usually, nickel or nickel-plated steel is used to make them because of its excellent conductivity and weldability. How is spot welding performed on lithium-ion batteries?
Spot welding is the recommended technique for joining parts of a lithium-ion battery because of several factors: Precision: Precise welds are made possible by the localized heat generation, which doesn’t damage nearby materials. In the process of making batteries, this is vital because too much heat can harm delicate cell components.
Selecting the correct nickel strips is crucial for successful spot welding of lithium batteries. Here’s some advice: Thickness: Choose nickel strips that are the appropriate thickness for the battery cells. Thicker strips provide more strength but may require higher welding power.
