Battery Tab Welder | Lithium Battery Tab Welding Machine

Service Overview

An ultrasonic battery tab welding machine uses high-frequency ultrasonic vibration to join battery tabs with current collectors through a solid-state welding process. The welding process is performed at low temperatures without melting the base materials or using additional filler materials.

The machine is mainly used in lithium battery cell assembly, especially for power battery manufacturing. Stable tab welding quality helps maintain reliable electrical connections and reduce contact resistance during battery operation.

The ultrasonic welding process includes electrical energy conversion, ultrasonic vibration generation, amplitude control, energy transmission, and solid-state bonding.

Working Principle of Battery Tab Welder

The battery tab welder joins electrode tabs and battery terminals through a controlled welding process. Welding parameters such as current, pressure and welding time can be adjusted according to different battery designs.

Applications

Battery tab welding machines are mainly applied in lithium-ion battery manufacturing processes, including:

- Lithium-ion battery cell production
- Pouch cell assembly
- Cylindrical battery manufacturing
- Prismatic battery production
- Battery research and pilot production lines
