摘要
MnO_(2)以其天然储量丰富、价格低廉、环境友好等优势常被用作超级电容器电极材料,但其较差的导电性限制了其应用,因而为获得优良电化学性能,MnO_(2)基复合材料的研究十分广泛。本文从不同维度MnO_(2)基复合材料的角度,对近年来其在超级电容器领域的研究和应用进行了综述。对MnO_(2)同碳材料、导电聚合物以及其他过渡金属(氢)氧化物复合所形成的球型结构复合材料以及一维、二维、三维复合材料的结构特点、合成方法、电化学性能进行了总结和对比。并对MnO_(2)基复合材料在超级电容器领域未来的研究重点进行了分析和展望。可为MnO_(2)基超级电容器复合电极材料结构的合理设计、构筑及电化学性能改善提供参考。
MnO_(2) is often used as the electrode materials for supercapacitors due to the advantages of abundant natural reserves,low price and environmental friendliness.However,the poor electrical conductivity limits its application.Therefore,MnO_(2)-based composites,which aims at obtaining excellent electrochemical performance,are widely studied.This paper reviewed the research and application of MnO_(2)-based composites in the field of supercapacitors in recent years from the perspective of different dimensions.The structural characteristics,synthesis methods and electrochemical performance of the spherical,one-dimensional(1D),two-dimensional(2D)or three-dimensional(3D)composites of MnO_(2) compounded with carbon materials,conductive polymers and other transition metal(hydrogen)oxides were summarized.The future research emphases of MnO_(2)-based composites in the field of supercapacitors were also analyzed and prospected.This work could provide the reference for the reasonable design and construction of the structure as well as the improvement of the electrochemical performance of MnO_(2) based composites for supercapacitor electrodes.
