Encapsulating-polysulfide electrolyte: An answer to practical lithium-sulfur batteries

Endowed with high theoretical specific energy(2600 Wh/kg) and low material cost, lithium-sulfur(Li-S) battery emerges as a promising candidate for the next-generation energy storage system. A working Li-S battery is in fact a liquid electrochemical system where the reaction of solid S/lithium sulfide(Li_(2)S) proceeds via dissolved lithium polysulfides(LiPSs) intermediates [1].
