Abstract

A high surface area electrode is made by retaining an electrode blank with one surface thereof horizontal and facing upward. The surface is then submerged in a liquid having particles of conductive material suspended therein. The particles in suspension are then allowed to precipitate out and onto the surface of the electrode. This process is repeated until a porous layer of particles of the desired thickness has formed on the surface. As a final step the particles are bonded to the surface using an appropriate bonding method such as a heat treatment.
