Abstract
A nickel electrode (14) for use in a storage cell (10) includes a porous nickel substrate (50, 52) and a cobalt oxide passivation layer (56) on the nickel substrate (50, 52). A mass of nickel hydroxide/oxide (54) is impregnated within the pores of the substrate (50, 52). The cobalt oxide layer (56) is preferably deposited on the nickel substrate (50, 52) by contacting the substrate (50, 52) with an aqueous solution of cobalt nitrate, removing the excess solution, and heating the substrate in an oxygen-containing environment to form cobalt oxide. The cobalt oxide layer (56) at the surface of the substrate (50, 52) acts as a passivation layer to prevent corrosion of the nickel substrate (50, 52).
