摘    要:综述了NiCo2O4及其复合材料常用的制备方法、NiCo2O4及其复合材料在超级电容器中的应用。指出直接生长在导电基体上的NiCo2O4电极材料相比其他通过与粘接剂和导电剂混合制成的电极材料具有更好的电化学性能;三维立体结构和多孔结构的电极材料也拥有较高的电容性能,其原因可能是由于多孔结构和三维结构为氧化还原反应提供了连续的网络和更多的活性位点。并对NiCo2O4及其复合材料存在的问题进行了分析并对发展趋势进行了展望。

Abstract: The commonly used prepare methods of NiCo2O4 and theirs composite materials and application of in supercapacitors were reviewed. The NiCo2O4 electrode material directly growth on a conductive substrate has better electrochemical performance comparing to the electrode material prepared by mixing adhesive and conductive agent, three-dimensional and porous electrode materials structure have high capacitance performance, which is attributed to that the porous structure and 3 d structure provides continuous networks and more active site for redox reaction. The problems existing in the NiCo2O4 and their composites materials were analyzed and the development trend was prospected.
