Abstract
A multi-layer electrode includes a current collector having opposing first and second major surfaces, a fused carbon layer formed over one or both of the major surfaces, a conductive adhesion layer formed over each fused carbon layer, and an activated carbon layer formed over each conductive adhesive layer. The multi-layer electrode can be incorporated into a high energy density, high power density device such as an electric double layer capacitor.
