Aluminum / nickel sheet for anode and cathode of Li-ion polymer battery

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.

Targray Battery Tabs Portfolio Summary
Our battery tab portfolio has been created to meet the requirements of today’s lithium-ion battery and energy storage manufacturers. It includes aluminum (Al) tabs for positive electrodes, copper (Cu) tabs for negative electrodes, Copper-plated Aluminum (Cu-Al) or Nickel (Ni) tabs, and aluminum-clad copper tabs. Materials are available with or without polypropolene film, and black or yellow DNP.

• Material and cladding options: Many varieties of nickel, copper, aluminum-based tabs
• Thickness: 0,010 – 0,150 mm
• Tolerance: +/- 10% on nominal thickness
• Width: 1,0 – 10 mm
• Packaging: Wound on spools or plastic core with side shields
• Customization: Custom dimensions for thickness and width can be produced on request

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.

• 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
