The copper and nickel strips shown above are both 0.20mm thick, and 0.15mm thick nickel is reported to also work. Further experiments are continuing to determine all the other thicknesses that would work. After seeing this, my research revealed that this is an old metal-workers trick when trying to spot-weld aluminum sheets to each other.
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.
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.
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?
To ensure successful lithium batteries’ spot welding, properly setting up and calibrating your spot welder is essential. Here’s a guide: Power Settings: Adjust the power settings on the spot welder according to the thickness of the nickel strips and the type of battery cells in use.
Width: Ensure the width of the nickel strips matches the size of the battery terminals for optimal contact and conductivity. Purity: Use high-purity nickel strips to minimize resistance and ensure efficient energy transfer during welding.
Follow these steps: Clean Battery Surfaces: Wipe the surfaces of the battery cells with a clean, dry cloth to remove any dirt, oil, or residue that could interfere with the welding process. Arrange Battery Cells: Arrange the battery cells in the desired configuration, ensuring they are aligned and spaced adequately for welding.

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 …
Nickel: A Catalyst for Spot Welding Copper. Given copper''s inability to directly support spot welding, nickel comes into play as a catalyst to indirectly spot weld copper. When a nickel weld is performed near copper with sufficient power, the heat generated is enough to melt not only the nickel but also the copper on the other side. This ...
