AC Impedance Spectroscopy at an Ultramicroelectrode in Molten Salts
1994
ECS Proceedings Volumes
Preserved Fulltext
By combining ac impedance spectroscopy with ultramicroelectrodes a powerful electrochemical tool becomes available with which to probe the nature of electrode processes in molten salts. We have shown that ac impedances up to 100 MOhm can be measured at microelectrodes within the range 0.1 Hz to 5 kHz and accurate parameters for all the electrochemical processes, be they Faradaic or non-Faradaic, measured. Simulation have been have been carried out for two working electrodes one a disc of radius
