Modeling Li/CF x -SVO Hybrid-Cathode Batteries

and kinetic parameters, the model simulations are first fit to dis- charge data from Li/CFx and Li/SVO batteries. The model simula- tions are then compared to discharge curves from Li/CFx-SVO hybrid-cathode batteries of various mix ratios, electrode thicknesses and geometric areas. Finally, limits on discharge rates and battery design are established, within which the model accurately predicts performance.

Modeling Transients in Li/CFx-SVO Hybrid-Cathode Batteries

This document describes a first-principles-based mathematical model developed to predict the transient voltage-time behavior of batteries having hybrid cathodes comprising a mixture of carbon monofluoride (CFx) and silver vanadium oxide (SVO). These batteries typically operate at low to moderate rates of discharge, lasting several years. However, newer applications demand highrate discharges from these batteries, although for a relatively short period of time. The model presented here is a very useful tool for design optimization and performance prediction of batteries under low-rate discharges as well as high-current pulses.
