Power Technologies
Versatile expanded metal foils for primary & secondary batteries, fuel cells, and electrolysis equipment.

he 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

Our expanded metal foils are also used in the fuel cell and electrolyzer industries where it is required that electrodes allow the flow of fluids. The unique open-area geometry of our proprietary expansion process makes our materials well-suited to be used as the catalyst substrate or gas diffusion layer of these applications. 

Our MicroGrid® expanded metal foils are well-suited for a variety of power technologies.

Primary Battery
Expanded MicroGrid® material is configured to meet conductivity, strength, and weight requirements for each specific battery chemistry. Engineers that use Dexmet’s expanded metal foils for current collector screens or as active material support structure significantly increase the active material density and electrode adhesion of their primary batteries.

Secondary Battery
The ability to expand materials at 25 micron (.001") has opened the opportunity for advanced 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.
