Improving the Reaction Kinetics by Annealing MoS₂/PVP Nanoflowers for Sodium-Ion Storage.

ABSTRACT: Under the ever-growing demand for electrochemical energy storage devices, developing anode materials with low cost and high performance is crucial. This study established a multiscale design of MoS₂/carbon composites with a hollow nanoflower structure (MoS₂/C NFs) for use in sodium-ion batteries as anode materials. The NF structure consists of several MoS₂ nanosheets embedded with carbon layers, considerably increasing the interlayer distance. Compared with pristine MoS₂ crystals, the carbon matrix and hollow-hierarchical structure of MoS₂/C exhibit higher electronic conductivity and optimized thermodynamic/kinetic potential for the migration of sodium ions. Hence, the synthesized MoS₂/C NFs exhibited an excellent capacity o
