Interwoven MXene Nanosheet/Carbon‐Nanotube Composites as Li–S Cathode Hosts

The complex surface chemistry that dictates the interaction between MXene and polysulfides – the formation of thiosulfate via consumption of –OH surface groups, followed by Lewis acid–base interaction between the exposed Ti atoms and polysulfides – is unravelled. Interweaving carbon nanotubes between the MXene layers creates a porous, conductive network with high polysulfide adsorptivity, enabling sulfur hosts with excellent performance even at high loading (5.5 mg cm–2).
