Abstract: The features of charge transfer in electrochemical cells with electrodes of various types and with an intercalated compound Ag$_x$HfSe$_2$ ($x$ = 0.1, 0.2) as an electrolyte were studied by the method of impedance spectroscopy. Based on the analysis of the obtained data, the presence of mixed electron-ionic conductivity in this compound was shown, and the numbers of ionic and electron transfer in these compounds were determined for the first time. The different nature of relaxation processes in mixed and ionic charge transfer is shown.

Keywords: hafnium diselenide, silver, intercalation, impedance, ionic and electronic conductivity.
