WebApr 30, 2024 · The ohm resistance between electrodes and electrolytes (R s), resistance of charge transfer (R ct) and “Warburg” impedance are all related to the reaction process in batteries [61]. By comparing the size of the semicircle, the R ct can be easily used to judge the conductivity, which is an advantage of this method. The Tafel equation is an equation in electrochemical kinetics relating the rate of an electrochemical reaction to the overpotential. The Tafel equation was first deduced experimentally and was later shown to have a theoretical justification. The equation is named after Swiss chemist Julius Tafel. " It describes how the electrical current through an electrode depends on the v…
