Electrostatic self-assembly of 2-dimensional MXene-wrapped sulfur composites for enhancing cycle performance of lithium–sulfur batteries

For lithium–sulfur (Li–S) batteries to be used in practical applications, the low conductivity of elemental sulfur and the shuttle phenomenon need to be overcome together with the preparation of cathode material of a high sulfur content. Herein, we report a two-dimensional (2D) delaminated MXene-wrapped sulfur composite ([email protected]) synthesized via facile electrostatic self-assembly. The ultrathin and flexible 2D MXene wrapping of sulfur...
