Battery Electrode - Anode & Cathode Materials
The electrically active material comprising 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 been providing expanded metal for 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.
