Fabrication of a nano-Li+-channel interlayer for high performance Li–S battery application

Abstract

A nano-Li⁺-channel interlayer was first proposed and successfully prepared for Li–S batteries, based on a totally new concept of separating the polysulfide particles via a size exclusion effect. The Li–S battery assembled with the interlayer exhibited much lower polysulfide permeability and better battery performance than that without the interlayer. This concept could help overcome the polysulfide permeating problems and shed light on the development of Li–S batteries.
