2,4-Difluorophenyl isothiocyanate as a redox mediator in the electrolyte for kinetically favorable Li–S batteries

Abstract

2,4-Difluorophenyl isothiocyanate (DPIC) was used as a redox mediator for a kinetically favorable electrolyte, and can boost the activation of insulating sulfur and sulfide, accelerate the bidirectional conversion reaction kinetics and restrict the undesirable shuttle effect, consequently ensuring high sulfur utilization and extended cycle lifespan of Li–S batteries.
