Kinetic Electrode Reactions in Silver Electrodeposition Using a Multipulse Current Measurement

The kinetics of electrode reactions in silver electrodeposition are investigated using a multipulse current measurement. The transient voltage drops across the anode and cathode electrodes in response to the applied multipulse currents are measured and analyzed with an analytical solution of unsteady-state equations comprising diffusion of ions, charge-transfer reactions, and a charging process of the electrochemical double layer. The measured voltage-time curves agree well with those predicted by the analytical solution. The kinetic constant, the exchange current density, and the double-layer capacitance, which characterize the kinetics of the electrode reactions, are determined
