摘要 本论文根据氢能技术——电解水制氢章节中的氧化还原“赝电容”理论,设计关于超级电容器电极材料制备与应用的研究型能源化工专业实验。本实验采用水热合成法,以Co(NO_(3))_(2)·6H_(2)O、Ni(NO_(3))_(2)·6H_(2)O为原料,水热合成“镍-钴甘油酸酯”,再以“镍-钴甘油酸酯”为前驱体,通过高温氧化制备NiCo_(2)O_(4)纳米球无机材料。利用电化学工作站的循环伏安法、恒流充放电和交流阻抗等技术测试所制备材料的电化学性能。 Based on the theory of redox“pseudo capacitance”in the water electrolysis chapter of hydrogen energy technology,this paper designs a research-oriented Physical-Chemical Experiment on the preparation and application of electrode materials for supercapacitors.In this experiment,“nickel cobalt glycerate”precursor was synthesized by hydrothermal method with Co(NO_(3))_(2)·6H_(2)O、Ni(NO_(3))_(2)·6H_(2)O as raw materials,and then“nickel cobalt glycerate”was used to prepare NiCo_(2)O_(4)nanospheres inorganic materials by high temperature oxidation.The electrochemical properties of the materials were tested by cyclic voltammetry,constant current charge discharge and AC impedance.
