Abstract : Accordingly, an object of this invention is to reduce the cost of manufacturing light weight, sintered nickel coated graphite fiber grid nickel electrodes. Another object of this invention is to provide a more efficient method of introducing cobalt into the nickel active material of sintered nickel coated graphite fiber grid electrodes. A further object is to provide a nickel electrode which uses less cobalt additive but more efficiently. Still another object of this invention is to provide a method of reducing the number of charge-discharge cycles required to bring a cobalt additive/nickel active material/sintered nickel coated graphite fiber grid electrode up to 90 percent of capacity. These and other objects of this invention are accomplished by providing a method of introducing a cobalt additive into a nickel active material/sintered nickel coated graphite fiber plaque composite electrode.
