Intermolecular cyclic polysulfides as cathode materials for rechargeable lithium batteries

Abstract

An intermolecular cyclic polysulfide (ICPS) is designed, synthesized, and applied as a cathode material in rechargeable lithium batteries for the first time. Three ICPSs are formed. During discharge, they are converted to lithium 1,3-benzenedithiolate and lithium sulfide. During recharge, the starting materials are recovered. This work adds new members to the organopolysulfide family.
