Making a better organic-inorganic composite electrolyte to enhance the cycle life of lithium-sulfur batteries

Abstract

A new methodology for resolving the long-standing obstacles of Li-S batteries by the synthesis of a composite gel polymer electrolyte with a unique internal structure is disclosed in this paper. The Li-S cells prepared using this novel electrolyte system exhibit high discharge capacities (1140 mA h g(-1) during the 1st cycle and reversible capacity of 970 mA h g(-1) at the 100th cycle) and improved cycle life.
