N,S-Doped Porous Carbon Nanobelts Embedded with MoS₂ Nanosheets as a Self-Standing Host for Dendrite-Free Li Metal Anodes.

ABSTRACT: Metallic Li is one of the most promising anodes for high-energy secondary batteries. However, the enormous volume changes and severe dendrite formation during the Li plating/stripping process hinder the practical application of Li metal anodes (LMAs). We have developed a sulfate-assisted strategy to synthesize a self-standing host composed of N,S-doped porous carbon nanobelts embedded with MoS₂ nanosheets (MoS₂ @NSPCB) for use in LMAs. In situ measurements and theoretical calculations reveal that the uniformly distributed MoS₂ derivatives within the carbon nanobelts serve as stable lithiophilic sites which effectively homogenize Li nucleation and suppress dendrite formation. In addition, the hierarchical porosity and 3D nanobelt networks ensure fast Li-ion
