Özet:

 

Electrochemical impedance spectroscopy (EIS) was employed to  investigate diffusion of AlCl4- ions in basic (AlCl3-NaCl-KCl)  molten salt.  Nyquist plots in different DC offset potentials showed  finite and restricted aluminum ion diffusion due to insertion and  blocking in the graphite electrode.  The general Warburg, open  Warburg, and short Warburg impedance in the complex Nyquist plot of  this system showed the anomalous diffusion behavior of the ions in the  graphite electrode.  The diffusion coefficient of the AlCl4- ions  was calculated from the slope of the Warburg line in a totally  blocking film in the graphite electrode and was found to be 2.8 \times  10-10 cm2/s.
