There is a growing interest in next generation all-solid-state lithium-ion batteries (LIBs), as well as their sodium counterparts, to avoid safety issues associated with the volatile liquid electrolytes now used. Solid electrolytes under investigation are polymers with dissolved Li/Na salts, inorganic oxide or sulfide ceramics, or composites of the two, but each have negative, as well as positive, characteristics.

The Wunder Lab at Temple University is investigating a new class of materials that are cocrystals of lithium (or sodium) salts and low molecular weight organic molecules, which have many favorable, properties such as low resistance grain boundaries, conductivities ~ 10-4 S/cm, and melt-castability. Professor Stephanie Wunder's talk will offer an overview of criteria for solid electrolytes and how these new cocrystals fulfill many of the desirable properties needed.
