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 1^st cycle and reversible capacity of 970 mA h g⁻¹ at the 100^th cycle) and improved cycle life.
