“…Thus, SnS/3DNG exhibited a high capacity of 509.9 mA h g −1 with a capacity retention of 87% after 1000 cycles at 2 A g −1 , which is much higher than that of SnS/3DG (45%). In addition to 3DNG, S‐doped, N‐rich carbon nanosheets have also demonstrated strong interactions with SnS, and the composite exhibited a fast Na storage performance.…”

High-efficiency energy storage technologies and devices have received considerable attention due to their ever-increasing demand. Na-related energy storage systems, sodium ion batteries (SIBs) and sodium ion capacitors (SICs), are regarded as promising candidates for large-scale energy storage because of the abundant sources and low cost of sodium. In the last decade, many efforts, including structural and compositional optimization, effective modification of available materials, and design and exploration of new materials, have been made to promote the development of Na-related energy storage systems. In this Review, the latest developments of micro/nanostructured electrode materials for advanced SIBs and SICs, especially the rational design of unique composites with high thermodynamic stabilities and fast kinetics during charge/discharge, are summarized. In addition to the recent achievements, the remaining challenges with respect to fundamental investigations and commercialized applications are discussed in detail. Finally, the prospects of sodium-based energy storage systems are also described.

“…Hence, the concern has focused on alloying‐ and conversion‐type materials such as silicon, phosphorus, metals, metal sulfides (SnS, SnS 2 , MoS 2 , etc. ), and metal oxides (SnO 2 , SnO, CuO, etc. ) due to their higher theoretical capacities arising from the redox of transition metals or the alloying/dealloying process during the discharge and charge process.…”

Sodium ion batteries (SIBs) are regarded as promising next‐generation energy storage devices due to their decent theoretical energy density and especially low cost. Here, micro/nanostructured Sb2O3 micro‐bundles consisting of many abreast nanoribbons were prepared via a simple hydrothermal route. In this unique structure, both ends of Sb2O3 nanoribbons with the thickness of ∼50 nm scatter with each other and extend radially from the center point, which not only reserves more space between nanoribbons to accommodate volume changes, but also provides plenty of open channels to facilitate the intimate contact of active species, conductive agents and electrolytes, thus efficiently shortening diffusion paths of Na+/e−. Evaluated as anode materials for SIBs, Sb2O3 micro‐bundles delivered outstanding electrochemical performance: high reversible capacity, superb rate capability, and stable cyclic ability. To get more insight, both the morphology evolution and the effect on electrochemical performance were explored as well, which further verified the significance of designing micro/nanostructured electrode materials in advanced energy storage fields.

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.
