Metallic‐state 2D SnS2 nanosheets with expanded lattice spacing and a defect‐rich structure were synthesized by the intercalation of Ni into the van der Waals gap of SnS2. The expanded lattice spacing efficiently enhanced the electrochemical performance of the SnS2 for sodium‐ion batteries owing to the change electron state density and energy band structure. In operando synchrotron XRD and theoretical calculations were used to gain insight into the influence of foreign metal‐ion doping and its location. The optimized architecture obtained by in situ uniform growth of nanosheets on carbon fibers significantly enhanced the electrochemical performance. The inherent advantages of this architecture are shorter paths for ion insertion and extraction, larger contact area for more sodium diffusion pathways, and superior electrolyte penetration. Benefiting from the Ni intercalated SnS2 bilayer, the internal adjustment of the electronic state and the enlarged interlayer spacing significantly enhanced the electron transport kinetics, which can be explained by the metallic‐state properties. The integrated electrode exhibited an initial high reversible capacity of 795 mAh g−1 at 0.1 A g−1, with a stable capacity retention of 666 mAh g−1 after 100 cycles. Good rate capability was also exhibited with specific capacities of 691, 564, 437 mAh g−1 at current densities of 200, 500, and 1000 mA g−1, respectively.

SnS /graphene composites have attracted extensive attention in energy storage owing to their excellent electrochemical performance. However, most of the previous methods to synthesize SnS /graphene composites require long times, high temperatures, or high pressures, which are obstacles for practical low-cost production. A simple one-pot strategy to prepare SnS /graphene composites has been developed, which is not time-consuming (1 h) and requires moderate temperature (75 °C) in atmosphere. Through this method, ultrafine SnS nanoparticles anchored on graphene nanosheets are prepared and exhibit excellent electrochemical performance for both lithium and sodium storage. Specifically, as anodes for lithium-ion batteries, the SnS /graphene electrode delivers a high capacity of 1480 mAh g after 50 cycles at 0.2 A g . Even at 10 A g , the SnS /graphene electrode can achieve a capacity of 666 mAh g . A constructed full lithium-ion cell exhibits a capacity of 957 mAh g after 50 cycles at 1 A g . This simple one-pot strategy may pave the way for large-scale production and practical application of SnS /graphene composites in energy storage.

In the scenario of renewable clean energy gradually replacing fossil energy, grid‐scale energy storage systems are urgently necessary, where Na‐ion batteries (SIBs) could supply crucial support, due to abundant Na raw materials and a similar electrochemical mechanism to Li‐ion batteries. The limited energy density is one of the major challenges hindering the commercialization of SIBs. Alloy‐type anodes with high theoretical capacities provide good opportunities to address this issue. However, these anodes suffer from the large volume expansion and inferior conductivity, which induce rapid capacity fading, poor rate properties, and safety issues. Carbon‐based alloy‐type composites (CAC) have been extensively applied in the effective construction of anodes that improved electrochemical performance, as the carbon component could alleviate the volume change and increase the conductivity. Here, state‐of‐the‐art CAC anode materials applied in SIBs are summarized, including their design principle, characterization, and electrochemical performance. The corresponding alloying mechanism along with its advantages and disadvantages is briefly presented. The crucial roles and working mechanism of the carbon matrix in CAC anodes are discussed in depth. Lastly, the existing challenges and the perspectives are proposed. Such an understanding critically paves the way for tailoring and designing suitable alloy‐type anodes toward practical applications.
