Results of a preliminary investigation into the use of a solid Li--Si electrode in a high-temperature fused salt secondary battery are reported. A series of measurements was made to characterize the voltage plateaus and to identify the alloy compositions corresponding to each. Entropy calculations were also made by measuring the variations in the potential of the alloy electrode vs. pure liquid Li at temperatures between 360 and 440/sup 0/C. It is concluded that the Li--Si electrode is promising as an excellent anode material for high-energy-density batteries.
