Abstract

A pyridyl-functionalized mesoporous graphene is developed to accommodate sulfur for Al–S batteries, which can significantly reduce the voltage hysteresis to ∼0.43 V. The reaction kinetics of the Al–S battery are accelerated by the catalyst-free carbon host, ascribed to both the mesoporous graphene structure and the covalently functionalized pyridyl groups.
