Behavior of blocked electrode/solid electrolyte interface in galvanoharmonic charging mode

Abstract

Electrochemical behavior of a cell with a blocked electrode/solid electrolyte interface is studied in the galvanodynamic charging mode. The possibility of application of simpler and more graphic calculation technique and separation of impedance of electrochemical systems into active and reactive components is shown. The applied equivalent circuits are both the Jacobsen-West model (correct for relatively large times or small ac frequencies) and the Grafov-Ukshe model (correct for relatively large ac frequencies). The plotting of the dependences of the active and reactive impedance components on ac frequency was used to find the values of parameters of the studied equivalent electric circuits.
