摘　　要：作为一种介于传统静电电容器和电池之间的新型储能器件,超级电容器的整体性能受限于电极材料。研究发现,赝电容材料拥有数十倍于碳基材料的比容量。而双金属氧化物作为一种新型赝电容材料,因其多重氧化态、多金属离子特性和高理论容量,在电化学储能领域备受关注。本工作系统介绍了双金属氧化物及其复合材料的合成及性质,对双金属氧化物及其复合材料在超级电容器电极材料方面的应用进行了简要概述,并展望了其发展前景和重点发展方向,以及需要解决的科学问题。Supercapacitors （SCs） have been regarded as ＇bridges＇ between traditional capacitors and batteries, and the integrated performance of SC is essentially determined by its electrode materials. It is found that the capacitance of pseudocapacitive electrode materials can be ten times higher than that of carbon-based electrode materials. As one of the most promising electroactive materials, binary transition metal oxides （BTMOs） and their corresponding composites have been widely studied for energy storage due to their rich redox properties involving multiple oxidation states and different ions. This review presents an extensive description of BTMO materials and the most commonly used synthetic methods. Furthermore, several notable BTMOs and their composites in the application of SCs are reviewed and their prospect and direction of development as well as the scientific problems remaining to be solved are pointed out.
