title: Entrapment of Polysulfides by a Black-Phosphorus-Modified Separator for Lithium-Sulfur Batteries.
abstract: A bifunctional separator modified by black-phosphorus nanoflakes is prepared to overcome the challenges associated with the polysulfide diffusion in lithium-sulfur batteries. It brings the benefits of the entrapment of various sulfur species via the strong binding energy and re-activation of the trapped sulfur species due to its high electron conductivity as well as Li-ion diffusivity.
