Supercapacitor Electrode Materials

The performance of supercapacitor electrode materials was greatly affected by the specific surface area. The urchin-like NiCo2O4 was transformed into porous NiCo2O4 (AA-NiCo2O[Formula: see text] using the acid–alkali treatment method. The specific surface area of AA-NiCo2O4 was 165.0660 m2/g, which was about three times larger than that of NiCo2O4. The specific capacitance of the AA-NiCo2O4 was enhanced significantly (1700 F/g at 1 A/g), and AA-NiCo2O4 possesses good rate capacitance (1277 F/g at 10 A/g). This is mainly attributed to the larger specific surface area, fast and convenient electron–ion transport and redox reaction. Therefore, AA-NiCo2O4 is a promising high-performance supercapacitor electrode material.

AbstractHerein, we introduce a simple method to prepare hierarchical graphene with a tunable pore structure by activating graphene oxide (GO) with a two-step thermal annealing process. First, GO was treated at 600 °C by rapid thermal annealing in air, followed by subsequent thermal annealing in N2. The prepared graphene powder comprised abundant slit nanopores and micropores, showing a large specific surface area of 653.2 m2/g with a microporous surface area of 367.2 m2/g under optimized conditions. The pore structure was easily tunable by controlling the oxidation degree of GO and by the second annealing process. When the graphene powder was used as the supercapacitor electrode, a specific capacitance of 372.1 F/g was achieved at 0.5 A/g in 1 M H2SO4 electrolyte, which is a significantly enhanced value compared to that obtained using activated carbon and commercial reduced GO. The performance of the supercapacitor was highly stable, showing 103.8% retention of specific capacitance after 10,000 cycles at 10 A/g. The influence of pore structure on the supercapacitor performance was systematically investigated by varying the ratio of micro- and external surface areas of graphene.
