POROUS CARBON OXIDE NANOCOMPOSITE ELECTRODES FOR HIGH ENERGY DENSITY SUPERCAPACITORS
摘要
<p>A high energy density supercapacitor is provided by using nanocomposite electrodes having an electrically conductive carbon network (15) having a surface area greater than 2,000 m2/g and a pseudo-capacitive metal oxide (16) such as MnO2. The conductive carbon network (15) is incorporated into a porous metal oxide structure to introduce sufficient electricity conductivity so that the bulk of metal oxide (16) is utilized for charge storage, and/or the surface of the conductive carbon network (15) is decorated with metal oxide to increase the surface area and amount of pseudo-capacitive metal oxide in the nanocomposite electrode for charge storage.</p>
