Characterization of aqueous secondary cells with ZSPICE-aSPICE-based simulator for electrochemical impedance

摘要

Reported here is the development of ZSPICE, a SPICE-based softwarepackage for modeling electrochemical impedance phenomena on a personalcomputer platform. ZSPICE allows the user to define an equivalentcircuit with linear and nonlinear circuit elements. The impedance ofthat circuit is then computed at the AC frequencies employed in themeasurement of the electrochemical impedance of the cell. The utility ofthis software is demonstrated in this initial report by comparingexperimental impedance data obtained from a Hughes alkaline nickelelectrode with results computed for an equivalent circuit using linearelements
