ABSTRACT:
The present invention relates to the preparation of essentially silica-free glasses which can be melted at low temperatures and which have compositions within the Li.sub.2 O--Al.sub.2 O.sub.3 and/or F--B.sub.2 O.sub.3 system. The glasses exhibit very high lithium ion mobility which, resulting in low electrical resistivity, has led to their consideration as solid membrane electrolyte-separators in such devices as the lithium metal-sulfur battery.
