Using activated carbon as the active material on aluminum foil is the industry standard for creating Electric Double-Layer Capacitors (EDLCs). Activated carbon provides the massive surface area required for charge storage, while the aluminum foil acts as the current collector to transport electrons. Dry electrode technology is a significant advancement in supercapacitor manufacturing, moving away from traditional "wet" slurry casting. In this process, activated carbon is mixed with a dry binder—typically PTFE—and mechanically sheared into a self-supporting film without the use of toxic solvents like NMP.
