MnO_2-碳复合材料在超级电容器中的应用研究进展

Research progress of MnO_2-carbon composite in supercapacitor

碳材料具有低成本、结构多样性以及相对稳定的电化学性能等优点,是构建三维自支撑电极材料的首选基底材料。二氧化锰(MnO_2)因具有高理论比容量、低成本、自然资源丰富和环境友好等特点,作为超级电容器电极材料备受科研人员关注。介绍了MnO_2-活性炭(AC)、碳纳米管(CNT)、碳纤维(CF)和石墨烯(GR)复合电极的研究进展,并对MnO_2-碳复合电极材料发展趋势进行了展望。

Carbon-based materials have particularly received increasing attention owing to their low cost,structural diversity and relatively inert electrochemistry.It was preferred basement materials to building threedimensional self-supporting electrode.MnO_2 with high theoretical specific capacity,low cost,abundant natural resources and friend environment,has been paid great attention as the supercapacitor electrode materials.The research progress of MnO_2-AC,CNT,CF and GR as composites electrode in the supercapacitor were introduced.The development trend of composites electrode was also prospected.
