Claim 15:
16. A method of forming an anode for a capacitor, comprising:
generating tunnels in a tunneled portion of an aluminum current collector such that the tunnels extend from a first face of the current collector to a second face of the current collector,
adding one or more active layers over the tunneled portion of the current collector such that all of the tunnels that extend from the first face of the current collector to the second face of the current collector and are under the one or more active layers have an average width greater than 2 μm and less than 10 μm and have an average tunnel density greater than 5 M/cm2 and less than 90 M/cm2, and
the one or more active layers including fused particles; and
fabricating the capacitor such that the anode is in electrical communication with a terminal that is accessible from outside of a case of the capacitor.
