A hierarchical carbonized paper with controllable thickness as a modulable interlayer system for high performance Li–S batteries

Abstract

The carbonized Kimwipes® (CK) interlayer has been found to be a modulable, low-cost hierarchical interlayer for Li–S cells, leading to a high discharge capacity with superior cycling stability and rate performance. This new interlayer is designed to allow controllable thickness for analyzing the polysulfide interception mechanism within the interlayer architecture.
