PREDICTED ENERGY DENSITIES FOR NICKEL-HYDROGEN AND SILVER-HYDROGEN CELLS EMBODYING METALLIC HYBRIDES FOR HYDROGEN STORAGE

Simplified design concepts were used to estimate gravimetric and volumetric energy densities for metal-hydrogen battery cells for the purpose of (1) assessing the characteristics of cells containing metal hydrides as compared to gaseous storage cells, and (2) comparing nickel cathode and silver cathode systems. The silver cathode was found to yield superior energy densities in all cases considered. The inclusion of hydride forming materials yields cells with very high volumetric energy densities that also retain gravimeteric energy densities nearly as high as those of gaseous storage cells. Such hydride containing cells may also offer higher reliability and/or longer life. /GMRL/
