Battery Tab Materials for Lithium-ion Cell Manufacturers

li-ion battery tab diagram

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

Targray is a trusted global supplier of tabs for lithium-ion batteries, serving cell manufacturers and energy storage companies worldwide. Our battery tab materials are engineered for optimal performance, safety, and compatibility with today’s most demanding battery cell designs. Whether you’re manufacturing pouch cells, cylindrical cells, or prismatic cells, our precision-engineered tabs are designed to meet your production and performance goals.

 

What Are Lithium-Ion Battery Tabs?

Battery tabs are critical current collectors that connect the electrodes of a lithium-ion cell to external terminals, enabling charge and discharge. Each cell includes anode tabs (typically copper or nickel-coated copper) and cathode tabs (typically aluminum).

Tabs must offer excellent electrical conductivity, thermal stability, and adhesion to electrode materials to ensure safe, long-lasting battery operation.
