The transient electrical response of electrochemical systems containing insertion reaction electrodes

Abstract

The transient electrical response of electrochemical systems containing an insertion reaction solid-solution electrode is derived using Laplace transform methods. An electrode impedance is first calculated which allows the response of the system to any input signal to be calculated, either for the electrode alone, or in combination with other circuit elements. Effects of finite length are included and steady-state ac response is also derived. The results are illustrated by calculation of the effect of a series resistance on the rate of charge accumulation in an electrode under voltage control.
