07 - 017Characterization of Sol-Gel-Derived Cobalt Oxide Xerogels as Elec-trochemical Capacitors. — Very fine cobalt oxide xerogel powders areprepared from CoCl2 by use of a unique solution chemistry associated with thesol-gel process. Thermal treatment has significant effects on the surface area,pore volume, crystallinity, particle structure, and corresponding electrochemicalproperties. The highest average specific capacitance obtained is 291 F/g for asingle electrode, and it corresponds to the CoOx xerogel electrode calcined at150 ◦C. — (LIN, CHUAN; RITTER, JAMES A.; POPOV, BRANKO N.; J.Electrochem.
