Lithium-ion Battery Tabs
Aluminum, Copper & Nickel tab strips and bars for battery packagingBattery Tab Materials for Lithium-ion Cell Manufacturers
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.
