Abstract

Triangular sweep voltammetry data for a number of commercially available carbons in 31 weight per cent are discussed. A capacity minimum of 10 μf/cm2 was observed about 0V vs. for five carbon blacks. Results indicated that the carbon blacks with internal structure were completely wetted; results with one activated carbon having fine micropores (<25Å) indicated partial wetting. Experimental methods for minimizing faradaic current and distributed capacity effects are discussed.
