Description

The overall objective of the formulation (developed by Dr. Sarwan S. Sandhu, professor of chemical and materials engineering) presented here is to employ it for the analysis and explanation of the experimental data being currently acquired on the lithium-based cell: [Li(s), solid lithium anode / LiFSI, lithium bis(fluorosulfonyl)imide in DME-dimethoxyethane (solvent) / CF(s), solid carbon monofluoride, cathode active material]. The formulation links the amount of charge involved during the discharge of the above-mentioned cell with the fractional conversion of the limiting reactant, CF(s). Furthermore, the cell discharge current at any time during its discharge period is related to the overall cell discharge process-activation energy barrier. The overall cell discharge process-activation energy barrier is assumed to be equal to the sum of cell voltage losses associated with the charge transfers at the cell electrode-electrolyte solution interfaces and the transport phenomena involving electrons and ions in the various cell components; for example, electron transport in the cell cathode components and lithium-ion transport in the cell electrolyte solution.
