Aluminum And Copper Clad Metal Tab For Lithium - Ion Battery Free Of Additional Welding

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.

1. No transfer welding operation, improve the yield
2. Reduce the resistance of positive ear
3. Low temperature discharge efficiency is higher than that of traditional electrode
4. Reduce heating of electric core and improve safety
5. Resistant to electrolyte corrosion and breaking.
