“…On the other hand, doping of heteroatoms can enhance the wettability of electrode material in the electrolyte solution and provide additional pseudocapacitance. 15 In the process of calcining melamine and citric acid, hydrogen bonds between the molecules can form a stable carbon skeleton and play a supporting role. Graphitic C 3 N 4 firstly obtained by melamine has good chemical stability, which can ensure that the structure of electrode will not change greatly during long charge/discharge life.…”

“…Activated carbonitride was obtained using a high-temperature solid phase method according to Shen et al 15 Citric acid and melamine with a molar ratio of 1:3 were stirred and bathed at 75°C to form a transparent solution, which was then dried at 80°C to obtain uniformly mixed powder. The mixed powder was calcined in N 2 atmosphere at different temperatures (700°C, 750°C, and 800°C) for 1 hour and decomposed into N-doped activated carbon (NC), denoted as NC-700, NC-750, and NC-800, respectively.…”

Summary Trimanganese tetraoxide (Mn3O4) is limited in supercapacitor application due to its poor electrical conductivity and cycle stability. An effective strategy for improving its electrochemical performance is to be combined with good conductive materials, such as carbon materials. A facile method was developed to prepare a Mn3O4/activated carbonitride composite (MONC) as electrode material for supercapacitor. Mn3O4 particles with small size were homogeneously grown on the surface of activated carbonitride (NC). Notably, the addition of NC not only improves the electrical conductivity of Mn3O4 but also serves as a supporting matrix to maintain the stability of the composite. Electrochemical characterization results show that the specific capacitance of the composite can reach 180 F/g at a current density of 0.5 A/g, which is two times higher than that of Mn3O4 at the same current density. After 2000 cycles, the specific capacitance of MONC can be maintained at 80.2% of the initial specific capacitance. The symmetric coin cell (SCC) assembled by MONC as positive and negative electrodes shows large voltage window, excellent cycle stability, and superior energy/power densities. This work will be one of important references for the application of other transition metal oxides in energy storage devices.

To enhance the performance of electrochemical capacitor, the nanostructured carbon materials with large surface area, appropriate pore distributions, suitable electronic conductivity and perfect chemical stability are pursued. Herein, the highly graphitized hierarchical porous carbon with well-defined porosity are fabricated. For the first time, the novel bicontinuous nanoporous copper is used as both the template and the catalyst to synthesize the porous carbon materials. The asprepared porous carbon demonstrates a high specific surface area of 1826 m 2 g À 1 benefitting from the bicontinuous nanoporous copper template and KOH activation. By electrochemical test, the nanoporous carbon material displays a specific capacitance of 210 F g À 1 at a current density of 0.2 A g À 1 within 6 M KOH aqueous solution. The material demonstrates excellent cycling stability with a 95.4% capacity retention for 10 000 cycles with a current density of 1 A g À 1 . The present work provides a facile approach for fabrication of carbon-based electrode materials for electrochemical capacitors.
