  • Patent number: 8313719
    Abstract: The present invention provides for the preparation of an “optimized” VPO4 phase or V—P—O/C precursor. The VPO4 precursor is an amorphous or nanocrystalline powder. The V—P—O/C precursor is amorphous in nature and contains finely divided and dispersed carbon. Throughout the specification it is understood that the VPO4 precursor and the V—P—O/C precursor materials can be used interchangeably to produce the final vanadium phosphates, with the V—P—O/C precursor material being the preferred precursor. The precursors can subsequently be used to make vanadium based electroactive materials and use of such precursor materials offers significant advantages over other processes known for preparing vanadium phosphate compounds.

  • Patent number: 5855809
    Abstract: This invention relates generally to inorganic ionic liquids which function as electrolytes and do not crystallize at ambient temperature. More specifically, this invention is directed to quasi-salt inorganic ionic liquids which comprise the reaction product of a strong Lewis acid with an inorganic halide-donating molecule. This invention is further directed to quasi-salt inorganic ionic liquid mixtures which comprise combinations of electrolyte additives and quasi-salt inorganic ionic liquids. These quasi-salt inorganic ionic liquid mixtures are useful electrolytes.

  • Patent number: 5763652
    Abstract: A nitrile compound or an amide compound is hydrolyzed in the presence of an inorganic acid or other acidic catalyst or an alkali metal hydroxide or other basic catalyst, and the by-produced ammonium salt of the acidic catalyst or the produced salt of a carboxylic acid and a base is electrodialysed to form an acid and ammonia or aqueous ammonia, or to form a base and ammonia. The obtained acid or base may be recycled as a catalyst for the hydrolysis of the nitrile compound or amide compound, and the obtained ammonia is reutilized as a nitrogen source for the nitrile compound or amide compound. Such amide compound may be produced by hydration of a nitrite compound in the presence of a manganese oxide.
