The nickel-hydrogen (Ni-H{sub 2}) cell is rapidly replacing nickel-cadmium (Ni-Cd) cell as the system of choice for aerospace applications where weight is crucial. The heavy-sintered nickel electrode used in this cell accounts for about 38% of the cell weight. The use of small diameter fiber nickel electrodes will reduce the weight and improve the specific energy of the state-of-the-art Ni-H{sub 2} cell by about 50%. One advantage of this small diameter nickel fiber material is the increase in the surface area available for the deposition of active material. Initial testing of this type of electrode is very promising. This electrode is also applicable to other nickel-based batteries, such as nickel-zinc, nickel-iron, and nickel-metal-hydride, both for space and commercial applications.
