A facile synthetic approach to nanostructured Li2S cathodes for rechargeable solid-state Li–S batteries

Abstract

Li–S solid state batteries, employing Li2S as a pre-lithiated cathode, present a promising low cost, high capacity and safer alternative to their liquid electrolyte counterparts, where dissolution of intermediate polysulfide species can result in loss of active material and a subsequent decrease in ionic conductivity. A nanostructured Li2S material would afford greater flexibility in optimising the cathode composite for more harmonious electrode–electrolyte interactions, yet facile routes to such nanoscale materials are limited. Here, we report a facile and scalable microwave approach to directly synthesize nanostructured Li2S from a glyme solution containing lithium polysulfides. As-synthesized Li2S presents an ideal architecture for the construction of free-standing cathodes for all-solid-state Li–S batteries.
