An improved reticulate electrode is produced by coating only one surface with a hydrophobic coating agent. Suitable hydrophobic coating agents include thermoplastic polymers such as polyolefins, polyhaloolefins, polyarylene sulfides and sulfone polymers. A preferred embodiment of the reticulate electrode is produced in a method which comprises: (a) affixing filaments to a support fabric to form a network of filaments, the filaments being comprised of a metal or metal sensitized plastic, (b) depositing an electroconductive metal on the filaments to form metal coated filaments, the deposition providing interfilament bonding at contact sites between adjacent filaments, (c) removing the support fabric from the metal coated filament network to produce a reticulate electrode having a porosity of at least 80 percent, and (d) depositing on only one surface of the reticulate electrode a coating of a hydrophobic coating agent. The novel reticulate electrodes have improved gas nucleation and release properties which result in reduced cell voltage when employed in electrolytic processes.
