Fundamental Electrode Kinetics 
For a complete understanding of the mechanism 
involved in any electrode reaction, it is necessary to 
study electrode kinetics in order to determine the 
important rate-limiting steps in the overall electrode 
reaction. 
A study was initiated and a report has been pre-
pared which presents the fundamentals of electrode 
kinetics and the methods used in evaluating the 
characteristic parameters of rapid-charge transfer 
processes at electrode—electrolyte interfaces. The 
modern concept of electrode kinetics is outlined, 
followed by a consideration of the theoretical prin-
ciples underlying the experimental techniques for the 
sophisticated investigation of electrode kinetics. 
Complete details are contained in: Electrode Ki-
netics, by John P. Elder, ANL-7072, Argonne 
National Laboratory, Argonne, Illinois, July 1965. 
Covered in the report are ohmic, mass-transfer, and 
charge-transfer overpotential, and the determination 
of charge-transfer kinetic parameters. Also presented 
is the theory governing the following experimental tech-
niques: voltametry, including both controlled-poten-
tial and controlled-current electrolysis: perturbation-
relaxation techniques, including both potentiostatic 
and galvanostatic methods; and alternating-current 
methods
