A multifunctional layered Ti3C2Tx/VS2 composite sulfur host for promoting the conversion of lithium polysulfides in lithium–sulfur batteries

A multifunctional sulfur host, Ti 3 C 2 T x /VS 2 , is developed by incorporating VS 2 onto the surface of few-layer Ti 3 C 2 T x using a self-assembly method. A 3D-printed Ti 3 C 2 T x /VS 2 /S cathode with high sulfur loading achieves high areal capacity.
