Several components of lithium-ion batteries - electrode metal foils (current collectors), tabs and output terminals - are welded together using technologies such as laser or ultrasonic welding. If these welds are inadequate, the electrical resistance between components will increase.
In weld quality testing, resistance values between components are measured to ensure weld quality. Weld quality testing is carried out in every process that involves welding, including welding of electrode sheet tabs as well as welding between collectors and output terminals.
Fusion welding, specifically using electron beams or lasers, is the best method for welding battery components. Both electron beam and laser welding offer high power densities, pinpoint accuracy, and are well-suited for automated welding processes and small, miniature weld applications.
