Metal Battery Tab Materials and Solutions

Our line of  battery tab materials has been created to meet the exact needs of today’s lithium-ion battery manufacturers industry. Available in cuts or rolls, our battery tab portfolio includes tabs for positive electrodes made from Aluminum (Al), tabs for negative electrodes made from Copper (Cu), and Copper-plated Aluminium (Cu plated Al) or Nickel (Ni) tabs. Targray li-ion battery tab materials are available with or without Polypropolene (PP) film, and black or yellow DNP.

The Role of Li-ion Battery Tabs in Battery Manufacturing

A typical large format lithium-ion cell uses copper foil as the anode current collector and aluminum as the cathode current collector. The 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 and allows 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.
