Battery Tab Materials for Lithium-ion Cell Manufacturers

li-ion battery tab diagram

Battery tabs play an important role in lithium-ion cell manufacturing. Typical large format lithium-ion cells use copper for the anode foil (current collector) and aluminum for the cathode foil. A ‘foil-to-tab’ weld is needed to gather all the current collector plates (foils) inside the cell and join them to a tab. The tab then exits the cell casing, which allows the cell’s energy to be transferred to an external source.

There are two foil-to-tab welds in each li-ion cell, and hundreds of cells in a standard lithium-ion battery pack.
