Abstract

A porous electrode, which may be charged with an active paste for use in alkaline accumulators, is made by coating a granular conductive or non-conductive material with a heavy electro-deposit of metal, e.g. Ni, Co, or Cd, so that the granules are formed into a rigid porous structure. Granules of Fe, Ni or carbon of uniform size are poured into a supporting structure of sheet or perforated metal, loosely compacted steel wool, ribbons or strands, and forms the cathode placed below an anode in the plating bath. The cathode may be magnetic to keep the particles from floating, or these may be pressed into position mechanically, or by centrifugal force. Preferably the granules are first soaked in a metal salt solution drawn into the body of granules before electrolytic deposition from the solution, and the granules may be pre-coated with copper. The rigid porous structure may then receive a further metal coating by applying nickel carbonyl in vapour, liquid, or dissolved form, and subsequently heating to decompose the carbonyl, and deposit nickel on the electrode, which may then be firmly bonded by sintering.
