Evolution of Stabilized 1T‐MoS₂ by Atomic‐Interface Engineering of 2H‐MoS₂/Fe−N_<i>x</i> towards Enhanced Sodium Ion Storage

Abstract Metallic conductive 1T phase molybdenum sulfide (MoS 2 ) has been identified as promising anode for sodium ion (Na + batteries, but its metastable feature makes it difficult to obtain and restacking during the charge/discharge processing result in part capacity reversibility. Herein, a synergetic effect of atomic‐interface engineering is employed constructing 2H‐MoS layers assembled on single atomically dispersed Fe−N−C (SA Fe−N−C) material that boosts reversible capacity. The work‐function‐driven‐electron transfer occurs from SA via Fe−S bonds, which enhances adsorption Na by , lays foundation sodiation process. A 2H 1T/2H MoS with ferromagnetic spin‐polarization sodiation/desodiation process, significantly storage kinetics, thus /SA display high electronic conductivity fast diffusion rate.
