Abstract

A porous TiO₂/BaTiO₃ heterostructure composite has been developed as a polysulfide mediator for lithium–sulfur batteries. Superior electrochemical performance has been achieved, mainly attributed to the synergy of TiO₂ and BaTiO₃ with dual affinity to polysulfides from chemical and ferroelectric-induced polarization effects, and enhanced redox kinetics propelled by the TiO₂/BaTiO₃ heterojunctions.
