The present paper is devoted to the study of the exchange current density of Re transfer in the high-temperature molten salt system using the Tafel dependencies. This data allowed precise information on the electrochemical behavior of the reaction mechanism. The exchange current density of the redox Re0/Re7+ pair was found to be 381.27 mA cm-2 at 773 K at 1 wt.% of KReO4 in KF-KBF4-B2O3 molten salt. The cathode transfer coefficient was calculated using the inclination angle tangent of Tafel graphs.
