中间相炭微球改性聚苯胺超级电容器电极材料研究
Polyaniline Electrode Materials Modified by Mesocarbon Microbead for Supercapacitor
摘要
Abstract
In this paper,polyaniline/activated mesocarbon microbeads (PANI/A-MCMB)composite material was obtained through in-situ chemical polymerization of aniline by using activated mesocarbon microbeads (MCMB ) as substrate and ammonium peroxydisulfate (APS ) as oxidizing agent.The morphology and structure of prepared PANI/A-MCMB composite material was characterized by scanning electron microscope (SEM)and X-ray diffraction (XRD).A symmetric redox supercapacitor was assembled with PANI/A-MCMB composite as active electrode material and 1.0 mol/L H2 SO4 aqueous solution as electrolyte, and the electrochemical properties of this PANI/A-MCMB supercapacitor were investigated by cyclic voltammetry (CV),electrochemical impedance spectroscopy (EIS)and galvanostatic charge/discharge tests.The experimental results show that the single specific capacitance of PANI/A-MCMB composite materials is 301.6 F/g at current density for 0.1 A/g,the specific capacitance is 276.3 F/g and the capacity retention is 91.6 % after 1000 charge/discharge cycles. PANI/A-MCMB composite materials have higher specific capacity and better cyclic stability than PANI electrode materials whose single specific capacitance of PANI is only 228 F/g and the capacity retention is 39.5% after 1000 charge/discharge cycles.关键词
