Lithium Battery Tabs/Aluminum Tabs/Nickel Tabs for Lithium Ion Battery Raw Material

• Battery tabs play an important role in lithium-ion cell manufacturing. A typical large format lithium-ion cell uses copper foil as the anode current collector and aluminum as the cathode current collector.
• A ‘foil-to-tab’ weld is needed to gather all the current collector plates (foils) inside the cell and join them to a tab which exits the cell casing, allowing the cell’s energy to be transferred to an external source.
• There are two foil-to-tab welds in each cell, and hundreds of cells in a typical lithium-ion battery pack.

The aluminum-clad copper material tab provides a low cost and high-performance solution for li-ion battery tab joining. Nowadays, the leads or tabs from Li-ion pouch and prismatic cells are often configured with one lead of copper and the other lead of aluminum. This brings a challenge for welding copper to aluminum with the busbar. By replacing one of the leads with an aluminum-clad copper tab, the busbar joining can be applied to all aluminum to aluminum connections. This greatly simplifies the welding process.

Material and cladding options: various nickel, copper, aluminum based labels
Thickness: 0010 – 0150 mm
Tolerance: plus or minus 10% of nominal thickness
Width: 1.0 – 10 mm
Packaging: wound on the spool or plastic core with side guard
Custom: custom sizes for thickness and width can be generated as required

The ease of machining and low electric resistance of this material make it best suited for such products as battery terminals.

• Free of additional welding process
• Reducing resistance of anode
• Lower discharge efficiency at low temperature than traditional tab and lead
• Reducing battery heating
• Excellent electrolytic corrosion resistance and breaking resistance
