ABSTRACT: Considering the great potential of composite electrode with carbon and
transition metal oxides as a future ideal form of electrode for future energy
storing system, many efforts have been devoted into such aspect of research.
Sweet potato-derived carbon framework with nanosheet form of MnO2 anchored on it was carried out through the low-temperature solution grown
technique, which is simple, low-cost, and applicable for large-scale commercial
production. Such form of composite electrode can facilitate the inner
transportation of electrons and ions, and offer high specific capacitance (309 F/g
at 0.5 A/g) with comparable discharging rate capability (94 F/g at 20 A/g),
which reasonably can be regarded as a superior form of composite electrode.
