Davis, S., Takeuchi, E. S., Tiedemann, W., & Newman, J. (2007). Simulation of the Li-CFx system. Journal of the Electrochemical Society, 154(5), A477-A480.
The Li-CFx system has been successfully used in implantable batteries to power medical devices for humans. Amassed data is analyzed to show that the behavior is dominated by the open-circuit potential and Tafel kinetics. Data from several discharge load resistances can be collapsed onto a single curve on this basis. At the low rates of interest, transport limitations can be neglected. Data for open-circuit relaxation show that the potential is a straight line when plotted against the logarithm of time. This is in harmony with the dominance of Tafel kinetics.
