Patent ID: 6899919

Claim:
A method of making a high surface area electrode comprising the steps of providing an electrode blank having a surface, providing means for supporting said electrode blank with said surface horizontal and facing upward, providing means to retain a liquid above said surface, providing means for draining liquid from above said electrode blank to a location below said electrode blank, providing a liquid, suspending metal electrically conductive particles in said liquid, filling said means for retaining with said liquid having electrically conductive particles suspended therein, allowing said electrically conductive particles to precipitate out of suspension and onto said surface and form a coating thereon, allowing said liquid to drain through said means for draining and out of said means for retaining, refilling said means for retaining with said liquid having electrically conductive particles suspended therein, allowing said electrically conductive particles to precipitate out of said liquid for a second time to form a thicker coating, allowing said liquid to drain through said means for draining and out of said means for retaining for a second time, and then bonding said electrically conductive particles to said surface.
