Abstract
Abstract This disclosure is directed to the preparation of nickel-plated organic polymer foam reticulate electrodes having open, interconnected cells and upon which nickel is deposited first electrolessly then electrolytically. The nickel-plated reticulate is subsequently impregnated with precursor salts yielding active nickel oxides and then compressed to obtain a compressed, nickel plated, reticulated polymeric foam reservoir containing active nickel oxides (also referred to as nickel oxide-hydroxide, viz., Ni(OH) 2 .
