SINGLE-ELECTRODE PELTIER HEATS OF LI-SI ALLOY ELECTRODES IN LICL-KCL EUTECTIC MELT

This paper reports single-electrode Peltier heats for cathodic (or ano dic) reactions of Li-Si alloy electrodes in coexisting phase states ev aluated from their thermoelectric power values. The thermoelectric pow er and thermodynamic properties for various coexisting phase states in Li-Si alloy were determined from electromotive force measurements of the following nonisothermal and isothermal cells, respectively (T) Li \ LiCl-KCl \ Li-Si (T + Delta T) and (T) Li \ LiCl-KCl \ Li-Si (T). Ge neral methods of estimating the thermoelectric power for a lithium all oy electrode from its thermodynamic properties have been developed the rmodynamically. The estimation methods were validated by detailed comp arison with experimental results of LiSi alloy electrode systems.
