Faradaic Admittance and Migration in the Diffuse Double-Layer: Effect on the Phase Angle

Abstract

The effect of migration in the diffuse double-layer on the phase angle between the alternating components of the faradaic current and voltage is discussed. It is shown that the cot Ø v. √ω relationship is nonlinear and the modified equation for this case (i.e. when migration is taken into account) is given. Equations derived already by Matsuda are discussed. Theoretical studies on the variation of ((I_o)_app/(I_o)_ms with Gouy potential are also reported.
