ABSTRACT:
A method of etching increases the surface area of a metal foil by creating uniformly distributed etch tunnels. The foil is pretreated by depositing a discontinuous surface layer of metal that is cathodic to the foil, followed by chemically etching the foil to remove a portion of the deposited metal. Finally, the foil is electrochemically etched to create the etch tunnels.
