Impedances of Ni electrodes and Ni/H2 cells from different manufacturersThe consistency of impedance measurements within each group of flightweigth Ni/H2 cells being tested for Space Station Freedom confirms that impedance measurements are reproducible provided that the same conditions of cycling and storage are maintained. However, electrodes and cells from different manufacturers vary widely, even with the same cycling and storage conditions. Measurements on cells from two manufacturers that have been cycled for 500-800 cycles show that there are not only major changes upon cycling, but there are substantial differences in the behavior of cells from different manufacturers with cycling.
