Cell Lab Ultrasonic Spot Welding Machine [Glovebox-Compatible | 40 kHz High-Frequency Welder | Cu & Al Tab Battery Welding]

Precision ultrasonic spot welder for copper and aluminium tab joining in lithium battery research

The Cell Lab Ultrasonic Spot Welding Machine is a compact, high-frequency system engineered for precision electrode tab welding in lithium-ion and solid-state battery development. Designed for glovebox integration, it enables reliable ultrasonic welding of copper and aluminium foils with excellent bonding strength and minimal heat-affected zones. Its stable 40 kHz frequency and 800 W output ensure clean, repeatable welds for pouch-cell, prismatic, and cylindrical formats — making it an essential tool for laboratory-scale cell assembly and pilot-line research.

Key Features

  • Glovebox-Compatible Design: Compact dimensions allow seamless installation inside inert-gas gloveboxes.

  • High-Frequency Ultrasonic Welding: Operates at 40 kHz for strong, uniform welds on aluminium and copper tabs.

  • Adjustable Power and Pressure: 800 W ultrasonic output with tunable gas pressure for diverse material combinations.

  • Fast and Reliable Operation: Welding completes within 0.2 s; welding head lifespan up to 1.5 million cycles.

  • Wide Material Compatibility: Supports Al and Cu foil thickness of 0.012 – 0.018 mm and up to 20 layers.

FAQ

Q1: What materials can this machine weld?
It is optimised for aluminium and copper electrode tabs up to 20 layers thick.

Q2: Is it suitable for use inside a glovebox?
Yes. Its compact design and low heat generation make it ideal for argon-filled environments.

Q3: How long is the welding cycle?
Each weld takes approximately 0.2 seconds for fast and efficient operation.

Q4: What is the expected lifetime of the welding head?
Up to 1.5 million welds under standard operating conditions.

Q5: Can the power and pressure be adjusted?
Yes. Both parameters are manually adjustable for different foil thicknesses and tab structures.
