摘要
以超级电容器实验为例,将绿色化学科学研究转化为实验教学的基本设计思路,学习双电层电容器和法拉第准电容器的工作原理、组装及性能测试方法(循环伏安法和恒流充放电法),分析循环伏安曲线、比电容、能量密度和功率密度,总结2者的不同。实践结果表明:电化学基础和科学研究的成功联通,让学生对电化学概念和原理有了更深刻的理解,并获得关于清洁能源储存器件的实践经验,同时也增强了学生的绿色化学素养。
The supercapacitor experiment was used as an example to illustrate the basic design ideas for converting scientific research of green chemistry into innovative teaching.The working principle and assembly process of two types of supercapacitors(Electric Double-Layer Capacitor(EDLC)and Faraday Pseudocapacitor)and tested performance via cyclic voltammetry(CV)and galvanostatic charge-discharge(GCD)had been studied.Finally,the differences between the two were summarized by analyzing the cyclic volt-ampere curve,specific capacitance,energy density and power density.The practical results showed that the electrochemical basics and scientific research had been connected successfully,which allowed students to gain additional insight into the concepts and principles of electrochemistry and receive valuable hands-on experiences on clean energy storage devices.Furthermore,students’green chemistry literacy also had been enhanced in the process of learning.
