Ea. Nizhnikovskii et al., IMPEDANCE METHOD OF EVALUATING CHEMICAL POWER SOURCES AND ITS APPLICATION TO THE TESTING OF LITHIUM-THIONYL CHLORIDE CELLS OF THE TL-1,2 TYPE, Russian journal of electrochemistry, 34(7), 1998, pp. 639-643
The problem of using impedancemetry to evaluate the state (in particul
ar, depth of discharge) of various chemical power sources is briefly o
utlined. Based on a literature analysis, an improved method for testin
g lithium-thionyl chloride cells is proposed. The method involves the
determination of impedance characteristics of the loaded cells. Experi
mental data are given that demonstrate the applicability of the method
to the evaluation of the state of lithium-thionyl chloride cells.
