ABSTRACT:
The invention provides a nickel foam and a method of forming a nickel foam for a nickel containing battery. An open-cell foam structure is placed in a nickel carbonyl gas containing structure. The foam structure is heated to a temperature at which nickel carbonyl decomposes. Nickel from the nickel carbonyl gas decomposes on the foam structure to form a nickel plated foam structure. The nickel plated foam structure is then sintered leaving an open-cell nickel network to form the nickel foam. The open-cells of the nickel foam comprise substantially hollow wires having a substantially uniform transverse cross-section. The nickel foam is further characterized by the conductivity through the nickel foam multiplied by a factor of 3.4 being equal to or greater than the theoretical conductivity of nickel.
