Abstract

The discovery of solids which exhibit high ionic conductivity has stimulated efforts to construct high energy density batteries utilizing such solids as the electrolytes [1]. The most common of these include alkali ion conductors such as polycrystalline Na β-alumina and NASICON. More recently, glasses in the form of borates, silicates, phosphates and others have also been shown to exhibit extremely high Li, Na, and Ag ion conductivity and are reviewed in a recent article by the authors [2]. Since glasses are isotropic and may be fabricated easily into complex shapes they would appear to be highly attractive alternatives to some of the polycrys-taline electrolytes mentioned above. Although a number of glassy electrolytes possess the required high ionic conductivities for cell operation, little or no information is available with regards to their corrosion resistance against potential reactants such as alkali metals, alloys and fused salts. As part of a program to investigate the potential of lithium borate based glasses as solid electrolytes, we have begun to investigate the reactions that occur at the glass-liquid lithium interface under both quiescent and ionic current flow conditions.
