Abstract

Abstract It is deduced that any n + 1 consequent points on a transient current curve of an electrode system with n time constants perturbed by a small amplitude of potential step can be correlated by a linear equation. Through regression of the linear equation, the electrochemical parameters and the number of time constants of the transient system can be easily obtained without a curve fitting process.
