Abstract
In an attempt to overcome problems associated with the reversible lithium electrode in organic solvent‐based electrolytes, the electrochemical characteristics of a number of binary and ternary lithium alloys in propylene carbonate have been studied. Thermodynamic and kinetic results for the Li‐Sn, Li‐Sb, and Li‐Bi systems are reported here. In each of these systems, one or more two‐phase regions with apparently rapid transformation kinetics at ambient temperature have been identified. Lithium chemical potentials and partial molar entropies for the alloys have been determined. Constant current charge‐discharge characteristics and diffusion coefficient data have also been obtained.Keywords
