Abstract

An electrode includes a current collector that is two-dimensional in shape and that contains perforations, and an intermediate layer that is electrically conductive and substantially corrosion-resistant. The intermediate layer is on at least part of a first surface of the current collector, and includes at least one of precious metal, graphitic carbon, a metal nitride, and a metal carbide. A first electrode layer is on the intermediate layer. At least part of the first electrode layer is in at least some perforations of the current collector. The first electrode layer, the intermediate layer, and the current collector are bonded together.
