RELATION BETWEEN CURRENT AND ACTIVATION POLARIZATION Preliminary measurements showed that the charge transfer process at the A1 electrode is quite fast. This means that the electrode process is very reversible and the observed overvoltages are mainly due to concentration polarization. It is there- fore necessary to use transient methods to investigate the electrode kinetics. We chose galvanostatic pulse measurements for this purpose. Galvanostatic Current Step Methods The galvanostatic technique, considering the double layer charging, was orig- inally discussed by Berzins and Delahay ( Ref. 2) e Since then, it has been used in several investigations ( Ref. 3). The change in potential resulting from the constant current through the electrode-melt interface is determined by the rate of charging of the double layer and the rate of mass transfer to the electrode, i.e.: where the symbols have their usual meaning. For a metal acti-vity of unity and for the boundary conditions, CO = Co” when x > 0 and t = 0, and G t 2 0: C8 when x = 03 and which gives xp (A’t) erfc (At1”) t exp (B’t) erfc ( Btl”) + 7T 1 / zPDF Image | NASA ALUMINUM CHLORINE BATTERY
