Se-Regulated MnS Porous Nanocubes Encapsulated in Carbon Nanofibers as High-Performance Anode for Sodium-Ion Batteries.

ABSTRACT: Manganese-based chalcogenides have significant potential as anodes for sodium-ion batteries (SIBs) due to their high theoretical specific capacity, abundant natural reserves, and environmental friendliness. However, their application is hindered by poor cycling stability, resulting from severe volume changes during cycling and slow reaction kinetics due to their complex crystal structure. Here, an efficient and straightforward strategy was employed to in-situ encapsulate single-phase porous nanocubic MnS_0.5Se_0.5 into carbon nanofibers using electrospinning and the hard template method, thus forming a necklace-like porous MnS_0.5Se_0.5-carbon nanofiber composite (MnS_0.5Se_0.5@N-CNF). The introduction of Se significantly impacts
