摘　　要：采用一步电沉积法在导电性能优异的碳布上生长二元镍铁硫化物纳米片作为超级电容器的电极,从而进一步提高其电化学性能。由于复合材料纳米结构具有较小的尺寸且表面粗糙多孔,为充放电过程中发生氧化还原反应提供了更加丰富的活性位点。同时,碳布作为基底,也进一步提高了复合材料的导电性。通过比较不同比例Ni-Fe-S/碳布复合材料的电化学性能,得到了性能最优异的比例,并对其进行了进一步的测试。复合材料的比电容在1 A/g时可达到770 F/g,并在40 A/g时容量可以保持在672 F/g。在进行10000次循环后,可保持初始值的92.3%。本研究对于二元金属硫化物/碳布复合材料作为超级电容器电极材料的发展具有一定的促进作用。We used a simple one-step electrodeposition method to grow binary nickel iron sulfide nano-ions on carbon cloth with excellent conductivity as electrodes for supercapacitors,which further improving its electrochemical performance.Because the nanostructure of the composite material has a small size and the surface is rough and porous,it provides more active sites for the redox reaction during the charge and discharge process.At the same time,the carbon cloth as a substrate further improves the conductivity of the composite material.By comparing the electrochemical performance of different ratios of Ni-Fe-S/carbon cloth composites,we obtained the ratio with the most excellent performance and carried out further tests on it.The specific capacity of the composite material can reach 770 F/g at 1 A/g,and the capacity can be maintained at 672 F/g at 40 A/g.After 10000 cycles,it can maintain 92.3%of the initial value.It is hoped that the research in this article will be helpful to the development of binary metal sulfide/carbon cloth composites as electrode materials for supercapacitors.
