摘要:
超级电容器是一种具有优异性质的新型储能器件,但能量密度低和成本较高的缺点阻碍其快速发展,开发高性能、低成本的电极材料是解决这些问题的有效途径. 本文通过采用溶剂热法成功制备出不同比例的钴镍复合物(Co-Ni),在此基础上加入稀土元素镱(Yb)成功合成Co-Ni-Yb三元纳米复合物,用X射线衍射(XRD)、透射电镜(TEM)表征其结构和形貌,且对其进行电化学性能测试(循环伏安法、恒电流充放电、稳定性测试). 结果显示Yb的加入明显缩短离子和电子传递途径,40:20:3的Co-Ni-Yb具有较好的电化学行为和较高的比电容(326.1 F/g). 因此,Co-Ni-Yb三元纳米片的成功合成为其在储能、催化、传感器等领域的应用开辟了道路.
Abstract:
Supercapacitors are a new type of energy storage device with excellent properties,but the disadvantages of low energy density and high cost hinder its development. Therefore,the development of high-performance and low-cost electrode materials is an effective way to solve these problems. In this paper,different ratios of cobalt-nickel complex(Co-Ni)were successfully prepared by solvent-heating method. Subsequently,the rare earth element ytterbium(Yb)was added on this basis to synthesize successfully Co-Ni-Yb ternary nanocrystals. Their structure and morphology were characterized by X-ray diffraction(XRD)and transmission electron microscopy(TEM),and their electrochemical performance tests were performed(cyclic voltammetry,constant-current charge/discharge,and stability test). The results showed that the incorporation of Yb led to a significant reduction in ion and electron transport pathways. It is noteworthy that the Co-Ni-Yb composite with a ration of 40:20:3 demonstrated enhanced electrochemical behavior and a high specific capacitance(326.1 F/g). Therefore,the successful synthesis of Co-Ni-Yb ternary layered nanocrystals opens the way for their applications in energy storage,catalysis,and sensors.
