锰氧化物/聚苯胺/石墨烯三元复合电极材料的制备及电化学性能
Preparation and Electrochemical Performance of Manganese Oxide/Polyaniline/Graphene Ternary Composite Electrode Materials
摘要
Abstract
Manganese dioxide/polyaniline(MP)composite was synthesized via a gas-liquid interfacial reaction between aniline gas and potassium permanganate aqueous solution,and then the ternary composite electrode material of manganese oxide/polyaniline/graphene(MPG)was prepared through hydrothermal treatment of the mixture of MP and graphene oxide.The chemical composition and structure were characterized by X-ray diffraction and Raman spectroscopy,and the micromorphology was observed by scanning electron microscopy.The results of electrochemical measurement manifest that MPG possesses a high specific capacitance of 251 F/g at 1 A/g,a favorable capacitance retention of 55%with scan rates from 10 up to 200 mV/s,and a high capacitance retention of 81%after 5 000 charging/discharging cycles at 5 A/g,demonstrating that the electrochemical performance of manganese-based electrode materials for supercapacitor can be effectively improved by the ternary composite method.关键词
