Few-layered V2C MXene derived 3D V3S4nanocrystal functionalized carbon flakes boosting polysulfide adsorption and catalytic conversion towards Li–S batteries

Few-layered V 2 C MXene derived 3D V 3 S 4 nanocrystal functionalized carbon flakes are controllably fabricated as an integrated host of sulfur for Li–S batteries, thanks to their strong chemical/physical adsorption and high catalytic activity.
