Solid-State Reaction Assisted Synthesis of Co-Doped MnO2 Nano-Composite Materials for Supercapacitor
In this work, a mechanically assisted solid-state reaction method was employed to prepare Co-doped MnO2 nanocomposites for supercapacitor electrode materials. It was found that the specific capacitance of 2.3 wt% Co doped MnO2 composite electrode was up to 340.1 F g-1 in 1.0 M KCl solution (Figure 1). Additionally, as prepared Co doped MnO2 composite electrode showed other desirable electrochemical properties, including good stable electrochemical properties, excellent reversibility and the long cycle life (Figure 2), demonstrating that it had potential advantages for the fabrication of electrochemical capacitor.
