摘　　要：超级电容器是一种具有使用温度范围宽、充电时间短、充放电效率高的新型绿色储能器件。本文首先介绍了超级电容器的研究背景和储能机制,总结了镍钴硫化合物这一类电极材料的优缺点和反应机理。然后重点阐述了目前镍钴硫化合物的主要制备方法及最新研究进展,如共沉淀法、水热/溶剂热法、电化学沉积法,并且介绍了制备条件对电化学性能产生的影响。最后指出了镍钴硫化合物存在的一些问题,并提出镍钴硫化合物与炭材料复合是未来这类电极材料的发展方向。Supercapacitor is a new type of energy storage device with a wide temperature range, short charging time, high charge and discharge efficiency, and environmental protection. Firstly, this paper introduced the definition and research background of supercapacitors. And we summarized the advantages and disadvantages of nickel-cobalt-sulfur compounds as electrode materials, and its reaction mechanism. The main preparation methods and research progress of nickel-cobalt-sulfur compounds are mainly described in this paper, such as co-precipitation method, hydrothermal/solvothermal method and electrochemical deposition method. In addition, the influence of reaction conditions on electrochemical properties was also introduced. Finally, the defects of nickel-cobalt sulfide are pointed out, and proposed that the hybrid of nickel-cobalt sulfide and carbon material is the future development of electrode materials.
