Abstract

A one-dimensional mathematical model for the lithium/thionyl chloride primary cell is used in conjunction with a parameter estimation technique, in order to estimate the electrode kinetic parameters of this electrochemical system. The electrode kinetic parameters include the anodic transfer coefficient and exchange current density of the lithium oxidation, _a,1 and i_0,1,ref; the cathodic transfer coefficient and the effective exchange current density of the thionyl chloride reduction, _c,4 and a⁰i_0,4,ref, and a morphology parameter, . The parameter estimation is performed on simulated data first in order to gain confidence in the method. Data reported in the literature for a high-rate discharge of an experimental lithium/thionyl chloride cell is used for an analysis.
