✦ Synopsis

Characterization of Sol-Gel-Derived Cobalt Oxide Xerogels as Electrochemical Capacitors.

-Very fine cobalt oxide xerogel powders are prepared from CoCl 2 by use of a unique solution chemistry associated with the sol-gel process. Thermal treatment has significant effects on the surface area, pore volume, crystallinity, particle structure, and corresponding electrochemical properties. The highest average specific capacitance obtained is 291 F/g for a single electrode, and it corresponds to the CoOx xerogel electrode calcined at 150
