摘要
设计了薄膜电极材料的制备及超级电容性能研究的综合性实验。运用电化学沉积的方法制备Co(OH)2薄膜电极材料,采用FESEM对基底与薄膜进行形貌表征,通过差热-热重对薄膜的热稳定性进行分析,重点考察了两种沉积温度对薄膜超级电容性能的影响。结果表明,50℃沉积温度下电流密度为4 A/g时,比容量可达2780 F/g,且分散阻抗较低。该实验原材料简单,过程容易实现,且涵盖薄膜材料制备、表征、性能分析等多个知识点。
The preparation of thin film electrode materials and the comprehensive experiment of supercapacitor performance were designed.Co(OH)2 thin film electrode material is prepared by electrochemical deposition,and the morphology of the substrate and the film is characterized by FESEM.The thermal stability of the film is analyzed by DTA-TG,and the effects of two deposition temperatures on the supercapacitance properties of the film are investigated.The results show that the specific capacity can reach 2780 F/g and the dispersion impedance is low when the current density is 4 A/g at 50℃.The experimental design is simple in raw materials and easy to implement.It covers many knowledge points such as preparation,characterization and performance analysis of thin film materials.
