Battery Tab Materials for Lithium-ion Cell Manufacturers

Lithium-ion Battery Tabs

Battery Tabs provide the connection between multiple layers of current collector plates and the external target source. The tab is welded to the current collectors (foil-to-tab) and then exits the cell, enabling the transfer of power to an external source.

Typically aluminium tabs are used for the cathode and Ni-plated copper used to form the anode, however other tab materials can be used for different cell chemistries and types.

Tab quality is crucial for the reliable and safe performance of a lithium ion cell; often cell failures can be attributable to poor tab sealing or inadequate corrosion resistance causing leaks.

Tab design is crucial for the optimised performance of a cell. Careful design considerations between tab thickness and width, as well as edge conditions and polymer types needs to be discussed.
