摘要：

利用简单的水热法制备出不同反应液浓度、不同反应时间以及不同反应温度氧化钴/泡沫镍（CoO/NF）电极，旨在改善氧化钴材料的比电容及稳定性。通过XRD、SEM、TEM、EDS Mapping和BET对其结构和形貌进行了表征，同时在1mol/L氢氧化钾（KOH）电解液中采用循环伏安曲线（CV）、充放电曲线（CP）、循环性能测试、大电流充放电测试以及交流阻抗（EIS）测试研究了其电化学性能。表征结果显示氧化钴均匀地分布在泡沫镍载体表面，且片状结构CoO-8h/NF具有较大的比表面积和多孔特性。在三电极体系中，电化学测试结果显示CoO-8h/NF在1mA/cm²电流密度下表现出最好的电容性能，比电容可以达到930mF/cm²。在10mA/cm²电流密度下对CoO-8h/NF电极进行10000次恒电流充放电测试，循环测试后电极的比电容几乎没有衰减，具有较好的稳定性，是超级电容器比较理想的正极材料。

Abstract:

Cobalt oxide/nickel foam (CoO/NF) electrodes with different concentration, reaction time and reaction temperature were synthesized by a simple hydrothermal method in order to improve its specific capacitance and stability. The phase structure, morphology and size of the prepared CoO-8h/NF were characterized by using fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), physical adsorption instrument (BET) and X-ray energy spectrometer (EDS and Mapping). The electrochemical activities of the cobalt oxide/nickel foam electrode were studied by cyclic voltammetry (CV), galvanostatic charge/discharge (CP), electrochemical impedance spectroscopy (EIS) and tested in 1mol/L potassium hydroxide (KOH) solution. The characterization results showed that cobalt oxide was evenly distributed on the surface of the nickel foam, and the flake structure CoO-8h/NF had large specific surface area and porous characteristics. In the three electrode system, electrochemical measurements confirmed CoO-8h/NF had the best capacitance performance at the current density of 1mA/cm² and its specific capacitance reached 930mF/cm². The CoO-8h/NF electrode was tested for 10000 times under the current density of 10mA/cm². After the cycle test, the specific capacitance of the electrode had almost no attenuation and had good stability, making it an ideal anode material for supercapacitors.
