A study on electrochemical impedance spectroscopy

Abstract

Electrochemical impedance spectroscopy (EIS) is an electrochemical technique which is used for determining various electrochemical processes occurs on electrode. This is also used for making batteries, to study corrosion etc. It is measured as opposition voltage when current is applied. EIS is interpreted by Nyquist and Bode plots. Many types of resistance, double layer phenomenon, zeta potentials etc. are studied by this process.
