The overall objective of the technology development program at the Lewis Research Center is to improve the components, design, and operating characteristics of Ni-H2 cells and batteries. As part of this effort a separator development program was designed to develop a separator that is resistant to penetration by oxygen and loose active material from the nickel electrode, while retaining the required chemical and thermal stability, reservoir capability, and high ionic conductivity. The performance of the separators interms of cell operating voltage was to at least match that of state-of-the-art separators while eliminating the present separator problems. The separators were submitted to initial screening tests and those which successfully completed the tests were built into Ni-H2 cells for short term testing. The separators with the best performance will be tested for long term performance and life.
