%X 基于红薯基制备活性炭，组装成超级电容器并借助电化学工作站对其电化学性能进行了测试，结果表明红薯基超级电容器的比电容可达237F/g。通过改进的高阶RC电路超级电容器模型，对其恒定电流充放电特性进行模拟，结果表明该模型能够精确描述恒流充放电过程中电压随时间的变化，总体来说具有较强的实用性。<br />
Based on the activated carbon prepared from sweet potato, the supercapacitor was assembled and its electrochemical performance was tested by electrochemical workstation. The results show that the specific capacitance of the supercapacitor can reach 237F/g. By improving the supercapacitor model of high-order RC circuit, the constant current charging and discharging characteristics are simulated. The results show that the model can accurately describe the change of voltage with time in the process of constant current charging and discharging, and has strong practicability in general.
