Title: Core-shell structured nanoparticles for lithium-sulfur cells

Abstract

Described is a core-shell nanoparticle comprising a lithium sulfide nanoparticle core and a shell covering the lithium sulfide nanoparticle core, the shell comprising at least one of carbon, polyanaline or a transition metal sulfide. The core-shell nanoparticle may be used for a positive electrode in a lithium/sulfur battery cell.
