Abstract
- Metallic conductive 1T phase molybdenum sulfide (MoS2) has been identified as promising anode for sodium ion (Na+) batteries, but its metastable feature makes it difficult to obtain and its restacking during the charge/discharge processing result in part capacity reversibility. Herein, a synergetic effect of atomic‐interface engineering is employed for constructing 2H‐MoS2 layers assembled on single atomically dispersed Fe−N−C (SA Fe−N−C) anode material that boosts its reversible capacity. The work‐function‐driven‐electron transfer occurs from SA Fe−N−C to 2H‐MoS2 via the Fe−S bonds, which enhances the adsorption of Na+ by 2H‐MoS2, and lays the foundation for the sodiation process. A phase transfer from 2H to 1T/2H MoS2 with the ferromagnetic spin‐polarization of SA Fe−N−C occurs during the sodiation/desodiation process, which significantly enhances the Na+ storage kinetics, and thus the 1T/2H MoS2/SA Fe−N−C display a high electronic conductivity and a fast Na+ diffusion rate.
