Based on MnO2/carbon cloth (CC) composite materials, an Ag-doped MnO2 nanowire, self-assembled, urchin-like structure was synthesized in situ the surface of CC using a simple method, and novel efficient flexible electrode material for supercapacitors developed. The morphology, structure, elemental distribution, pore distribution were analyzed SEM, TEM, XRD, XPS, BET. electrochemical performance tested cyclic voltammetry (CV) galvanostatic charge/discharge (GCD). In three-electrode system, GCD testing showed that specific capacitance reached 520.8 F/g at 0.5 A/g. After 2000 cycles current density 1 A/g, retention rate 90.6%, demonstrating its enormous potential application supercapacitor materials.
