Method for producing a reticulate electrode for electrolytic cells
First Claim
1. A method for producing a reticulate electrode for use in the electrolysis of aqueous solutions of ionizable compounds which comprises:
- (a) affixing filaments to a support fabric to form a network of filaments, said filaments being comprised of a metal or metal sensitized plastic,(b) depositing an electroconductive metal on said filaments to form metal coated filaments, said deposition providing interfilament bonding at contact sites between adjacent filaments, and(c) removing said support fabrics from said metal coated filament network to produce a reticulate electrode having a porosity of at least 80 percent.

Abstract
An electrode for use in the electrolysis of aqueous solutions of ionizable compounds is produced by a method which comprises affixing filaments to a support fabric to form a network of filaments. An electroconductive metal is deposited on the filaments to form metal coated filaments. During the metal deposition, interfilament bonding takes place at contact sites between adjacent filaments. Removing the support fabric from the metal coated filament network produces a reticulate electrode having a porosity of at least about 80 percent. The three dimensional electrodes are highly conductive, have high internal surface area, and are mechanically strong.
