Phosphorene as a promising anchoring material for lithium-sulfur batteries:a computational study
Effectively trapping lithium polysulfide(Li2Sx)species on host materials is an effective method to suppress the polysulfide shuttle,thus enhancing the cycling stability of Li–S batteries.In this work,by means of density functional theory(DFT)computations,we explore the adsorption and diffusion of various Li2Sx clusters on a phosphorene monolayer.Our results reveal that all the Li2Sx species can moderately bind with phosphorene,exhibit ultrahigh diffusivity along the zigzag direction,and enhance the electrical conductivity of phosphorene.Given these exceptional properties,it is expected that phosphorene can be utilized as a promising anchoring material for high-efficiency Li–S battery cathodes.
