A TiS2/Celgard separator as an efficient polysulfide shuttling inhibitor for high-performance lithium–sulfur batteries

In this work, we adopted a simple solid-phase sintering method to synthesize TiS₂ and further modified the Celgard membrane by vacuum filtration, and found that the TiS₂-VF/Celgard membrane can restrain the shuttling effects of polysulfide.
