Constructing carbon nanotube-optimized hollow Ti3C2 MXene hierarchical conductive networks for robust lithium–sulfur batteries

Ti 2 C 2 @N-CNT composites enhanced the adsorption and catalytic conversion of LiPSs, and simultaneously facilitated rapid ion diffusion and electron transfer. The reversible capacity reached 4.3 mA h cm −2 at a sulfur content of 4.8 mg cm −2 .
