Thin and Flexible Solid State Electrolytes for Ambient and Middle Temperature Storage Systems
By using adjusted and optimized electrolytes for each electrode in the Li/S battery, intrinsic parasitic effects like the polysulfide shuttle mechanism or electrolyte degradation at the side of the alkaline metal anode could be prevented. As an alternative to commercialized lithium-based batteries sodium-based systems become more and more popular. Due to the low melting temperature of sodium (about 100 °C), it is conceivable to use molten sodium as an anode separated with a thin, flexible and stable solid state electrolyte from a cathode. With this design a formation of dendrites and a reaction with the liquid electrolyte could be reduced and improved cycling stability can be obtained.
