A New Design for the High-Performance Sodium-Sulfur Battery

This paper describes a new design for the sodium-sulfur battery employing a new cell construction including a new method to join the solid electrolyte tube with the sodium reservoir made of metal, and an improved composition of the cell case to solve the problems of premature cell destruction and capacity decrease associated with our conventional design. As a result a higher and more stable performance of the new design than that of our conventional design has been shown through various evaluation tests.
