Versatile expanded materials for primary & secondary batteries, fuel cells and hydrogen generation applications.
The electrically active material compromising the electrodes of most advanced 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.

  • Active Material Support Structure
  • Engineered Geometry For Open Area
  • Single-Unit for Superior Conductivity


Power Technologies
Dexmet produces open area materials in metals and plastics for advanced batteries, fuel cells and gas generation equipment.

Primary Battery
Configured to meet the electrode requirements for each specific battery chemistry. The versitility of expanded materials to meet specific conductivity, strength and weight requirements are reasons why battery expert choose Dexmet's MicroGrid materials.

Secondary Battery
The ability to expand materials at 25 Micron (.001") has opened the opportunity for battery designers to utilize the benefits of expanded materials typically only seen in Primary batteries.

Electrolyzers & Fuel Cell
Expanding is the most economical way of creating an open area product from expensive and exotic materials. Dexmet can expand materials from niobium, zirconium, titanium and nickel to meet your stack requirements.
