简要回顾了利用界面电容和电极/溶液界面表面氧化还原过程的电化学双电层和超级电容器的相关基础。讨论和比较了电化学双电层容量、超级电容器电荷存储电极材料容量和超级电容器容量测定的实验方法。指出了内在的局限性和陷阱;对流行的错误、误解和错误进行了评估。讨论了现有方法的适用性，并提供了实用的建议。
Relevant fundamentals of the electrochemical double layer and supercapacitors utilizing the interfacial capacitance as well as superficial redox processes at the electrode/solution interface are briefly reviewed. Experimental methods for the determination of the capacity of electrochemical double layers, of charge storage electrode materials for supercapacitors, and of supercapacitors are discussed and compared. Intrinsic limitations and pitfalls are indicated; popular errors, misconceptions, and mistakes are evaluated. The suitability of available methods is discussed, and practical recommendations are provided.
