“…Generally, b = 0.5 suggests a typical diffusion-controlled procedure, while b = 1.0 represents capacitive-controlled behavior. 46 As shown in Figure 6b, the b values of five peaks were calculated to be 0.84, 0.80, 0.88, 0.92, and 0.85, which are much closer to 1.0, elucidating that the capacitive process mainly controlled the whole electrochemical process of the FeSe 2 @NDC NB electrode. Furthermore, the capacitive contribution at various scan rates can be calculated according to the following equation…”

Thanks to their high conductivity and theoretical capacity, transition metal selenides have demanded significant research attention as prospective anodes for sodium-ion batteries. Nevertheless, their practical applications are hindered by finite cycle life and inferior rate performance because of large volume expansion, polyselenide dissolution, and sluggish dynamics. Herein, the nitrogen-doped carbon (NC)-coated FeSe2 nanoparticles encapsulated in NC nanoboxes (termed FeSe2@NDC NBs) are fabricated through the facile thermal selenization of polydopamine-wrapped Prussian blue precursors. In this composite, the existing nitrogen-doped dual carbon layer improves the intrinsic conductivity and structural integrity, while the unique porous yolk–shell architecture significantly mitigates the volume swelling during the sodium/desodium process. Moreover, the derived Fe–N–C bonds can effectively capture polyselenide, as well as promote Na+ transportation and good reversible conversion reaction. As expected, the FeSe2@NDC NBs deliver remarkable rate performance (374.9 mA h g–1 at 10.0 A g–1) and long-cycling stability (403.3 mA h g–1 over 2000 loops at 5.0 A g–1). When further coupled with a self-made Na3V2(PO4)3@C cathode in sodium-ion full cells, FeSe2@NDC NBs also exhibit considerably high and stable sodium-storage performance.

“…In addition, the synergistic coupling among Sb 2 S 3 , FeS 2 and the external carbon layer shortens the electron/ion transport pathway and ensures structural stability during cycling. Therefore, Sb 2 S 3 @FeS 2 as an anode material for SIBs exhibits 537.9 mA h g −1 rate capability at 10 A g −1 [111].…”

“…The high chemical affinity of the NiS2 nanosheet surface for sodium ions was confirmed by first-principles density flooding theory (DFT) calculations (Figure 14c). Moreover, the energy barrier reveals that the NiS2 (100) surface shows a lower energy barrier than that of the NiS2 (111) surface. The NiS2/pCMT provided a high energy density of 136 Wh kg −1 when used as an anode material for sodium-ion batteries [93].…”

The metal chalcogenides (MCs) for sodium-ion batteries (SIBs) have gained increasing attention owing to their low cost and high theoretical capacity. However, the poor electrochemical stability and slow kinetic behaviors hinder its practical application as anodes for SIBs. Hence, various strategies have been used to solve the above problems, such as dimensions reduction, composition formation, doping functionalization, morphology control, coating encapsulation, electrolyte modification, etc. In this work, the recent progress of MCs as electrodes for SIBs has been comprehensively reviewed. Moreover, the summarization of metal chalcogenides contains the synthesis methods, modification strategies and corresponding basic reaction mechanisms of MCs with layered and non-layered structures. Finally, the challenges, potential solutions and future prospects of metal chalcogenides as SIBs anode materials are also proposed.

Designing multiphase composition is believed to availably boost the structural integrity and electrochemical properties of sodium-ion battery anodes. Herein, a conceive of nanoflowers, assembled with Bi 2 S 3 nanorods, is demonstrated to construct the multiphase composition involving TiO 2 coating and polypyrrole (PPy) encapsulation. Bi 2 S 3 acted as the dominating active material, in consideration of the low content of TiO 2 , which ensured the high capacity of the composite. The dual-structural restrain of the TiO 2 and PPy coatings can effectively alleviate volume variation based on the pseudo-"zero-strain" effect of TiO 2 and high flexibility of PPy shells. Meanwhile, the heterointerface greatly enhanced the coupling effect between Bi 2 S 3 and TiO 2 and thus improved the electrochemical performance, which was proved by the results of density functional theory calculation and electrochemical tests. Combining the regulation from the Bi 2 S 3 /TiO 2 heterojunction and the dual-structural restrain effect, the Bi 2 S 3 /TiO 2 @PPy electrode exhibited excellent rate performance and superior cycle stability (275.8 mA h g −1 over 500 cycles at 10 A g −1 ). This study indicates that designing multiphase composition can be very promising and provides a structural insight to construct high stability in electrodes for sodium-ion batteries.
