“…As a typical representative of pseudocapacitive materials, MnO 2 has attracted great attention as a good candidate for electrode materials owing to its rich sources, low price, and excellent electrochemical performance (theoretical specific capacitance of 1370 F/g) [ 14 , 15 ]. MnO 2 can obtain various forms under different process conditions, and its most common crystal forms are α-MnO 2 , β-MnO 2 , γ-MnO 2 , δ-MnO 2 , and λ-MnO 2 [ 16 , 17 , 18 ]. These MnO 2 isomers fully utilize their respective advantages based on their tunnel size and crystal type [ 19 ].…”

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