CAPACITIVE ENERGY STORAGE USING HIGH SURFACE AREA TRANSITION METAL COMPOUNDS

HIGH SURFACE AREA MATERIALS HAVE DIVERSE APPLICATIONS, SUCH AS FOR ENERGY STORAGE SYSTEMS AND FOR CATALYTIC CONVERTERS. IN PHASE I, HIGH SURFACE AREA MATERIALS WILL BE PREPARED USING THE SOL-GEL PROCESS IN PHASE I. VARIOUS ELECTRICALLY CONDUCTIVE TRANSITION METAL OXIDES, NITRIDES, AND BORIDES WILL BE PREPARED AND STUDIED BY MEASUREMENT OF THEIR DOUBLE LAYER CAPACITANCE (WHICH IMPLIES ENERGY STORAGE CAPABILITY PER UNIT AREA). THE EFFECT OF THE SOL-GEL PROCESSING CONDITIONS (SUCH AS PRECURSORS CONCENTRATION, VISCOSITY AND DRAWING SPEED) ON THE THICKNESS OF THE POROUS COATINGS WILL ALSO BE DETERMINED, WHILE MAKING THICK POROUS COATINGS. THESE COATINGS WOULD BE USED AS ELECTRODES. AN ENERGY STORAGE DEVICE WILL BE DESIGNED, AND ITS ENERGY STORAGE CAPABILITY WILL BE EVALUATED, BASED ON THE USE OF THESE NEW SOL-GEL DERIVED ELECTRODES. THE EXPERIMENTAL RESULTS WILL BE USED TO OPTIMIZE THE PROCESS IN ORDER TO ACHIEVE THE BEST ENERGY STORAGE TECHNOLOGY.
