摘要:
在过渡金属氧化物中,二氧化锰(MnO2)是法拉第电容器的重要电极材料,因其具有易得、价廉、无毒、环境友好等优点,近年来一直是电化学储能电极材料的研究热点.以Ni网为基底,通过一步电化学沉积的方法制备了具有球形结构的MnO2粒子,基底良好的导电性以及复合材料的3维结构使得在电化学反应时增加了电极材料与电解液的接触面积,因而使得电极的电化学性能大幅度提高:该电极在200 mA·g-1的电流密度下的首次放电比电容达到146.9 F·g-1,且经过1 000次循环后,比电容保持率为91.1%,显示出较高的放电比容量和良好的循环性能.
Abstract:
In the transition metal oxides,manganese dioxide(MnO2)is one of the important electrode materials for the Faraday capacitors.Due to it have a lot of advantages,such as the low cost,non-toxic,environmentally friendly,and so on.In recent years,MnO2 has been the research focus of electrochemical energy storage electrode materials.In this paper,based on Ni network,MnO2/Ni composite was prepared by the electrochemical deposition MnO2 particles with spherical structure,the basal good electrical conductivity and three-dimensional structure,which can increasing the contact area of the electrode materials and electrolyte improve the electrochemical performance of the MnO2/Ni composite materials,the discharge specific capacitance of MnO2/Ni can be up to 146.9 g·F-1 at the current density of 200 mA·g-1 with retention rate of 91.1% after 1 000 charging-discharging,it shown high discharge specific capacity and good cycle performance.
