| | Objective:
- Develop and demonstrate an optimized nickel electrode for nickel-hydrogen cell with
improved specific energy and specific volume.
Approach:
- Select alternate nickel fiber plaques to replace the heavy-sintered nickel powder plaque
- Auburn University
- Bekaert Fibre Technologies
- Memtec America Corp
- Ribbon Technology

Advantages of the Nickel Fiber Substrates over the SOA
Nickel Powder Substrate:
- Smaller fiber diameter
- Larger surface area
- Higher porosity
- Dimensionally stable
- Lighter in weight
