ABSTRACT:
A process for producing a lightweight electrode grid by exposing a heated t of dense graphite fibers to Ni(CO).sub.4 gas wherein the Ni(CO).sub.4 decomposes upon contact with the graphite fibers depositing nickel metal coating on the graphic fibers. The nickel coated graphite fibers are then sintered to form the grid. Nickel or cadmium electrodes are made by attaching a current collector to the grid and impregnating the grid with the appropriate nickel or cadmium active material.
