Synthesis and Kinetic Analysis of «-MnO2 Nanowires for Supercapacitor Electrode

Abstract

As the electrode material of supercapacitor, MnO2 materials have attracted extensive concern and its electrochemical performance has been continuously optimized, but the kinetic analysis is rarely discussed. Herein, a-MnO2 nanowires with a uniform morphology were synthesized by hydrothermal method, which exhibits proven electrochemical property like outstanding circulation stability, demonstrated rate performance and high specific capacitance. In addition, diffusion-controlled Faradaic procedure and surface capacitance action were calculated and analyzed in detail.
