“…The ZnS:SnS@rGO and ZnS:SnS@CNTs were prepared in a similar way, but with the addition of GO and CNTs in a quantity equal to the 2 wt % of the yield of ZnS:SnS. Functionalized CNTs were acquired commercially from Sigma-Aldrich, whereas GO was produced by the modified Hummer’s method . Typically, graphite powder (2 g, Unichem <20 μm synthetic) and NaNO 3 (5 g, Sigma-Aldrich, 99–100.5%) were mixed thoroughly with concentrated H 2 SO 4 (160 mL, Sigma-Aldrich, 95–97%) in an ice bath and stirred for an hour.…”

The development of innovative materials with excellent electrochemical properties is immediately needed to dispel the problems of battery performance. In the present study, the hydrothermal method was applied to synthesize bimetallic sulfides (ZnS:SnS), which were then anchored on reduced graphene oxide (rGO) to produce ZnS:SnS@rGO composites or combined with carbon nanotubes (CNTs) to achieve ZnS:SnS@CNT composites. These composites were then investigated as electrodes for sodium-ion batteries, and their charge storage properties were analyzed. Nanostructures and the morphology of the as-prepared composites were examined by X-ray diffraction, scanning or transmission electron microscopy, and X-ray photoelectron spectroscopy. The specific charge capacity for the ZnS:SnS@CNT composite reaches 364 mA h g–1, while the ZnS:SnS@rGO composite shows 343 mA h g–1 at 0.1 C. Moreover, the inclusion of the conductive matrices also stabilizes the cycle life and rate capability even up to 5.0 C. Nyquist plots obtained as a result of impedance spectroscopy illustrate that the ZnS:SnS@CNT composite electrodes enable fast charge transfer due to lower charge transfer resistance of 44.4 Ω as compared to ZnS:SnS@rGO (i.e., 51.5 Ω) and bare ZnS:SnS (i.e., 68 Ω) electrodes. Electrochemical analysis proves that the presence of dual metal-sulfide ions combined with reduced graphene or CNTs as a conductive matrix results in considerably improved ion storage properties owing to the enhanced electronic conductivity, cushioned volume expansion, and provision of ionic transport highways through the electrode.

“…The energy spectrum of C 1s can be deconvolved into three peaks (Figure 4b), the main peak at 283.9 eV is associated with CC/CC, while the small peaks at 284.3 and 285.6 eV belong to CN/CS and CO, respectively. [25,47] The N 1s spectral profile (Figure 4c) shows the characteristic peaks of pyridine N (397.8 eV), pyrrole N (399.4 eV), and graphite N (401.3 eV). [31,48] The nitrogen groups in the carbon matrix can provide strong polar interactions with polysulfides, thus leading to an effective confinement effect for sulfur species.…”

Sodium-ion batteries (SIBs) are raising more attention due to their low cost and the natural abundance of sodium, which is of great potential applications in largescale energy-storage grids in recent years. [4][5][6][7][8][9][10] Nevertheless, SIBs anodes suffer from sluggish dynamics and structure pulverization issues owing to the larger ionic radius of Na + , leading to poor cycling performance and fast capacity degradation during sodiation/desodiation reaction. [11][12][13][14] Thus, it is urgent to develop the anode electrode for SIBs to realize the ideal Na + sodiation/desodiation and alleviate the strain and stress from the volume changes during charging and discharging.A variety of anode materials have been explored in SIBs, including carbonaceous materials, [15][16][17] alloy materials, [18,19] metal oxides/sulfides, etc. [20][21][22] Among all the materials, metal sulfides (MS x , M = Sn, Sb, Fe, etc.) have been considered as the promising anode candidate with high theoretical specific capacity and abundant resources. [23][24][25][26][27] However, the MS x anode shows inferior electrochemical properties due to the dramatically irreversible volumetric expansion and poor ionic/electronic dynamics. Several attempts have been proposed to solve these problems, including building porous carbon-based MS x composites and designing conventional nanoengineering, which can be an effective improvement to mitigate the volume variation to a certain extent and reduce the ion diffusion distance. [23][24][25][26]28] In spite of these approaches, the MS x composites with a high specific capacity, high rete performance, and stable cycling are still a key and challenging point now.Recently, two-phase MS x composites and heteroatom-doped carbonaceous have been evidenced to exhibit good electrochemical performance. [29][30][31][32][33] For example, Cao et al. reported a hierarchical heterogeneous structure of bimetal sulfide (FeS 2 @Sb 2 S 3 ), which extremely accelerates the electronic/ion transport and effectively alleviates the volume expansion upon long cyclic performance. [31] In addition, they are also coming up with a heterointerface engineering of hierarchical Bi 2 S 3 / MoS 2 , which proves to exert low Na + adsorption energy and fast diffusion kinetics for SIBs due to the charge redistribution at the boundaries of Bi 2 S 3 /MoS 2 . [32] Unfortunately, there are still Heterointerface engineering with multiple electroactive and inactive supporting components is considered an efficient approach to enhance electrochemical performance for sodium-ion batteries (SIBs). Nevertheless, it is still a challenge to rationally design heterointerface engineering and understand the synergistic effect reaction mechanisms. In this paper, the two-phase heterointerface engineering (Sb 2 S 3 and FeS 2 ) is well designed to incorporate into N-doped porous hollow carbon nanofibers (Sb-Fe-S@CNFs) by proper electrospinning design. The obtained Sb-Fe-S@CNFs are used as anode in SIBs to evaluate the electrochemical performance. It delivers a ...

“…Similar to the structure of SIBs, SICs also make up of cathode and anode materials, current collectors, electrolytes, separators, and metal shell. [ 87–89 ] In SICs, the electrode materials serve as the core of energy storage and consists of a battery‐type electrodes and a capacitor‐type electrodes. [ 90 ] The current collectors play a role of carrying active materials and collecting currents.…”

In the past 10 years, preeminent achievements and outstanding progress have been achieved on sodium‐ion capacitors (SICs). Early work on SICs focussed more on the electrochemical performance. While it is easy to confirm which specific electrodes exhibit excellent properties, it is difficult to understand the mechanisms which are most promising for the next generation of SICs. From the early research in supercapacitors iterations to the present well‐developed Na‐ion batteries, the evolution of the controversial pseudocapacitive mechanism for SICs has been full of breakthroughs and back tracing steps. Moreover, as the research has progressed and the interests have changed, different emphases on the different subdisciplines (cell configurations, flexible devices, and presodiation technologies) have increased. In this review, first, the electric double layer mechanism, battery‐type mechanism, and the controversial pseudocapacitance mechanism are systematically analyzed and compared. Subsequently, mechanism‐oriented SICs cell configurations with different cathode and anode mechanisms are discussed. Moreover, the characteristics and features of electrode materials in different SICs cell configurations are summarized. Finally, key technologies and possible future developments are discussed. This review summarizes SICs from a broad and macro perspective from mechanisms to cell configurations, from cathodes to anodes, and from history to future, and offers a deep understanding of SICs devices.
