ABSTRACTThe nickel-hydrogen (Ni-H2) 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-H2 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-metalhydride, both for space and commercial applications.

Understanding of catalytic processes requires detailed knowledge of the catalyst. As heterogeneous catalysis is a surface phenomena the understanding of the atomic surface structure of both the active material and the support material is of utmost importance. This work is a high resolution electron microscopy (HREM) study of different phases found in a used automobile catalytic converter.The high resolution micrographs were obtained with a JEM-4000EX working with a structural resolution better than 0.17 nm and equipped with a Gatan 622 TV-camera with an image intensifier. Some work (e.g. EDS-analysis and diffraction) was done with a JEM-2000FX equipped with a Link AN10000 EDX spectrometer. The catalytic converter in this study has been used under normal driving conditions for several years and has also been poisoned by using leaded fuel. To prepare the sample, parts of the monolith were crushed, dispersed in methanol and a drop of the dispersion was placed on the holey carbon grid.
