Vanadium disulfide (VS2) emerges as a great potential anode material for sodium-ion batteries (SIBs) owing to its large layer spacing and high specific capacity. However, the severe capacity decay ambiguous sodium storage mechanism severely impair merits. Herein, nano-micro floral spherical VS2 is designed performance enhancement in ether-based electrolyte deciphered. The undergoes multiple mechanisms, involving traditional reaction of VS2↔NaVS2↔Na2S unique Na2S↔Na2Sx (2 < x <8) ↔S8 facilitated by Cu collector. Meanwhile, reactions trigger decomposition-reassembly original structure form hierarchical porous framework that mitigates stress generated volume changes. Notably, molecular dynamics simulations electrochemical measurements indicate not only facilitates Na+ de-solvation diffusion, but also endows electrode with speedy diffusion kinetics. Consequently, demonstrates an outstanding reversible 655.8 mAh g-1 after 900 cycles at ultra-high 20 A g-1. In addition, assembled Na3V2(PO4)3//VS2 full battery achieves superior cycling stability average decayed rate 0.069% per cycle. This work can provide precious insights into development advanced metal-sulfide materials.

Abstract Optimizing electrochemical kinetics by regulation ion/charge transfer efficiency and stabilizing the electrode structure of materials is crucial to maximize rapid charging long cycling sodium‐ion storage. Herein, VS 2 /Bi S 3 spring‐type heterointerfaces hollow microspheres with spatial confinement sulfur vacancy defects are synthesized as a fast‐charging anode for hybrid capacitors (SIHCs). The experimental studies coupled density functional theory calculations verify that strong coupling between Bi induces stable built‐in electric field, largely promoting charge efficiency. Sulfur at produce additional pseudocapacitive storage, which improves reversible capacity large‐rate fast performance electrode. Finite element analysis in situ expansion test confirm heterostructured formed flat‐morphology zigzag‐morphology stacking mitigate lattice contraction during insertion/extraction, accommodate mechanical stresses, maintain integrity heterojunction interface. When employed coin SIHC, it achieves high energy/power 135 Wh kg −1 /22 kW , an ultralong life 50 000 cycles; assembled pouch SIHC (1 Ah) demonstrates specific energy 120 10 C, 95.5% retention after 1000 cycles.
