“…The pyrolysis of polymers is a simple and efficient approach for preparing carbonaceous materials, which has been widely used to in situ decorate the MMSs. Various polymers, such as poly(styrene-acrylic), [70] polydopamine (PDA), [71][72][73][74][75] poly(3,4-ethylenedioxythiophene), [76] polyacrylonitrile, [77] dextrin, [78] and polypyrrole [79,80] have been used as precursors to generate highly conductive carbon materials. For example, a carbon-coated Fe 9 S 10 @MoS 2 heterostructure was developed by Liu and co-workers.…”

By virtue of the advantageous features of diverse material species, compositions, crystalline phases, valence states, architectures, and controllable nanostructures/ morphologies, metal sulfides manifest high electrochemical activity for sodium storage. Numerous metal sulfides have been applied for sodium storage and show promising electrochemical results. [36-38] Metal sulfides usually have higher electronic conductivity compared to metal oxide counterparts. [39,40] And the bond energy of M-S in metal sulfides is weaker than the M-O in metal oxides, leading to faster kinetics during the conversion reactions. [41] Among the metal sulfides based electrode materials, mixed metal sulfides (MMSs) with mixture phases of different metal sulfides demonstrate richer redox reactions and higher electronic conductivity compared to the single-component metal sulfides, showing intrinsic advantages for sodium storage. [39] For MMSs, it is verified that the phase boundaries at the heterointerfaces can provide abundant lattice mismatches, distortions, and defects, which have great influences on the charge carrier transport behavior by regulating the reaction kinetics and long-range disorder. [42] Meanwhile, driven by the internal electric field at the heterointerfaces due to the dissimilar coupling components with different bandgaps, the interfacial reaction kinetics and electron/ion transport can be greatly promoted. [43] Additionally, owing to the synergetic effect of different components, the uniformly dispersed intermediate nanocrystals during electrochemical reactions can avoid the aggregation of generated metal nanoparticles thus obtaining good cyclability. [44] And the diverse redox potentials and out-of-step electrochemical reactions of different components would mitigate the strain during sodium uptake/extraction processes. [45] Therefore, it is inferred that MMSs with suitable compositions could achieve excellent electrochemical performance. In general, the sodium storage mechanisms of metal sulfides are attributed to the combination of insertion, conversion, and/or alloying reactions. [37,46,47] During these reactions, the electrodes inevitably undergo severe volume change, which causes the collapse and pulverization of the structures and fading of capacity during repeated cycling. To address these issues, nanostructure engineering and compositing with conductive carbonaceous materials are reliable strategies for boosting the sodium storage properties of MMSs. [39] The nanostructured electrodes have several structure-dependent merits, resulting from the nanosized building units, large surface Sodium-ion batteries (SIBs) have drawn enormous attention in the past few years from both academic and industrial battery communities in view of the fascinating advantages of rich abundance and low cost of sodium resources. Among various electrode materials, mixed metal sulfides (MMSs) stand out as promising negative electrode materials for SIBs considering their superior structural and compositional advantages, such as decent el...

“…[54,55] This is positive because strong coupling effect will occur at the heterointerface due to the heteroatoms doping induced electron cloud bias, thereby effectively accelerating the electron transport and offering more active sites for Na + /K + storage. [56] In view of the successfully doped N into the carbon shell, the material is expected to exhibit an enhanced ionic diffusion rate, which will benefit the rate capability.…”

Conversion-alloying type anode materials like metal sulfides draw great attention due to their considerable theoretical capacity for sodium-ion batteries (SIBs) and potassium-ion batteries (PIBs). However, poor conductivity, severe volume change, and harmful aggregation of the material during charge/discharge lead to unsatisfying electrochemical performance. Herein, a facile and green strategy for yolk-shell structure based on the principle of metal evaporation is proposed. SnS 2 nanoparticle is encapsulated in nitrogen-doped hollow carbon nanobox (SnS 2 @C). The carbon nanoboxes accommodate the volume change and aggregation of SnS 2 during cycling, and form 3D continuous conductive carbon matrix by close contact. The well-designed structure benefits greatly in conductivity and structural stability of the material. As expected, SnS 2 @C exhibits considerable capacity, superior cycling stability, and excellent rate capability in both SIBs and PIBs. Additionally, in situ Raman technology is unprecedentedly conducted to investigate the phase evolution of polysulfides. This work provides an avenue for facilely constructing stable and high-capacity metal dichalcogenide based anodes materials with optimized structure engineering. The proposed in-depth electrochemical measurements coupled with in situ and ex situ characterizations will provide fundamental understandings for the storage mechanism of metal dichalcogenides.

“…The key point to achieve high-performance SIBs relies on the rational design of electrode materials with satisfactory Na ions insertion/extraction performance during repeated cycles, especially for the active anode host materials. Among the various anode materials, transition metal sulfides (M x S y ) have drawn extensive attentions due to their high sodium storage capacity [7][8][9][10]. Moreover, the weaker M-S bond than M-O bond is more kinetically favorable for electrochemical conversion reaction, leading to a better redox kinetics and reversibility [11].…”

Improving the cycling stability of metal sulfide-based anode materials at high rate is of great significance for advanced sodium ion batteries. However, the sluggish reaction kinetics is a big obstacle for the development of high-performance sodium storage electrodes. Herein, we have rationally engineered the heterointerface by designing the Fe1−xS/MoS2 heterostructure with abundant “ion reservoir” to endow the electrode with excellent cycling stability and rate capability, which is proved by a series of in and ex situ electrochemical investigations. Density functional theory calculations further reveal that the heterointerface greatly decreases sodium ion diffusion barrier and facilitates charge-transfer kinetics. Our present findings not only provide a deep analysis on the correlation between the structure and performance, but also draw inspiration for rational heterointerface engineering toward the next-generation high-performance energy storage devices.
