COMPARISON OF POTENTIAL STEP AND TRIANGULAR VOLTAGE SWEEP METHODS OF DOUBLE-LAYER CAPACITANCE MEASUREMENTS,

Abstract

A comparison was made of the potential step and triangular voltage sweep methods for obtaining the double-layer capacitance of a porous electrode. Electrolytic capacitors varying from 2000 to 27,800 microfarads were used as standards. The effects of faradaic current were investigated. A linear relationship, independent of capacity, was found between the error in the capacitance measurement and the faradaic current for the potential step method. The potential sweep method gave slightly better results than did the potential step method in the presence of a changing faradaic current. Distributed capacity effects were not considered in the study. (Author)
