THIN FILM COMPOSITE ELECTROLYTES, SODIUM-SULFUR CELLS INCLUDING SAME, PROCESSES OF MAKING SAME, AND VEHICLES INCLUDING SAME

摘要

Thin film composite electrolyte structures are disclosed that are preferably ionically conductive but not electronically conductive and are therefore suitable for use in electrochemical cells, such as secondary batteries based on sodium and sulfur. Vehicles including the electrochemical cells are also disclosed.
