NOVELTY - A compound comprising (a) at least one neutral, positive, or negative increased binding energy hydrogen species having a binding energy (i) greater than the binding energy of the corresponding ordinary hydrogen species, or (ii) greater than the binding energy of any hydrogen species for which the corresponding ordinary hydrogen species is unstable or is not observed because the ordinary hydrogen species binding energy is less than thermal energies or is negative; and (b) at least one other element, is new.    USE - In batteries, fuel cells, cutting materials, light weight high strength structural materials and synthetic fibers, cathodes for thermionic generators, photoluminescent compounds, corrosion resistant coatings, heat resistant coatings, phosphors for lighting, optical coatings, optical filters, extreme ultraviolet laser media, fiber optic cables, magnets and magnetic computer storage media, and etching agents, masking agents, dopants in semiconductor fabrication, fuels, explosives, and propellants.    ADVANTAGE - The compounds have unique properties which distinguish them from the same compound comprising ordinary hydrogen, if such ordinary hydrogen compound exists. The unique properties include unique stoichiometry; unique chemical structure; at least one extraordinary chemical properties such as conductivity, melting point, boiling point, density, and refractive index; unique reactivity to other elements and compounds; stability at room temperature and above; and stability in air and/or water. Formation of a hydride ion having a binding energy greater than 0.8 eV, i.e. hydrino hydride ion, allows for production of alkali and alkaline earth hydrides having enhanced stability or slow reactivity in water. In addition, very stable metal hydrides can be produced with hydrino hydride ions. Increased binding energy hydrogen species form very strong bonds with certain cations and have unique properties with many applications such as cutting materials (as a replacement for diamond); structural materials and synthetic fibers such as novel inorganic polymers. Due to the small mass of such the hydrino hydride ion, these materials are lighter in weight than present materials containing other anions. The power of hydrino hydride battery is more than 10000 times the power of ordinary batteries. The hydrino hydride battery possesses energy densities of greater than 100000 watt hours per kilogram.
