Anode and Cathode Battery Electrode Materials

The electrically active material used in the electrodes of most modern battery designs are powders and require a mechanical support structure to hold them in place during the manufacturing process. This support structure also functions as a current collector and provides the electrical connection point for the external circuit.

Dexmet has provided expanded metal foil used in anode and cathode production for many decades. While most designs are proprietary, the battery chemistry generally determines the alloy used, while the active material composition determines the optimum mesh geometry.
