Anti Corrosion Nickel Solder Tabs For Lithium Ion Battery Production Line current collector

battery aluminum tab and Nickel tabs for lithium ion battery production line

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.

Our battery label combination can be used for aluminum (AL) sheet of positive electrode, copper (Cu) sheet of negative electrode, copper-plated aluminum (Cu al) sheet or nickel (Ni) sheet and aluminum-clad copper sheet. Material with or without polypropylene film, black or yellow DNP.
