Sodium ion batteries (SIBs) have drawn significant attention owing to their low cost and inherent safety. However, the absence of suitable anode materials with high rate capability and long cycling stability is the major challenge for the practical application of SIBs. Herein, an efficient anode material consisting of uniform hollow iron sulfide polyhedrons with cobalt doping and graphene wrapping (named as CoFeS@rGO) is developed for high‐rate and long‐life SIBs. The graphene‐encapsulated hollow composite assures fast and continuous electron transportation, high Na+ ion accessibility, and strong structural integrity, showing an extremely small volume expansion of only 14.9% upon sodiation and negligible volume contraction during the desodiation. The CoFeS@rGO electrode exhibits high specific capacity (661.9 mAh g−1 at 100 mA g−1), excellent rate capability (449.4 mAh g−1 at 5000 mA g−1), and long cycle life (84.8% capacity retention after 1500 cycles at 1000 mA g−1). In situ X‐ray diffraction and selected‐area electron diffraction patterns show that this novel CoFeS@rGO electrode is based on a reversible conversion reaction. More importantly, when coupled with a Na3V2(PO4)3/C cathode, the sodium ion full battery delivers a superexcellent rate capability (496.8 mAh g−1 at 2000 mA g−1) and ≈96.5% capacity retention over 200 cycles at 500 mA g−1 in the 1.0–3.5 V window. This work indicates that the rationally designed anode material is highly applicable for the next generation SIBs with high‐rate capability and long‐term cyclability.

“…Figure 4a shows the cyclic voltammetry (CV) curves of the Fe 1−x S@PCNWs/rGO film electrode in the voltage range of 0.01-2.3 V (vs Na/Na + ) at a scanning rate of 0.1 mV s −1 . [16,27,34,35] As for the anodic scan, two oxidation peaks around 1.44 and 1.83 V are attributed to the desodiation reactions (2Na 2 S + Fe ↔ Na 2 FeS 2 + 2Na + + 2e − ; Na 2 FeS 2 ↔ Na y FeS 2 + (2 −y)Na + + (2 −y)e − ), where Na 2 FeS 2 and Na y FeS 2 species are formed.

Smart construction of ultraflexible electrodes with superior gravimetric and volumetric capacities is still challenging yet significant for sodium ion batteries (SIBs) toward wearable electronic devices. Herein, a hybrid film made of hierarchical Fe1−xS‐filled porous carbon nanowires/reduced graphene oxide (Fe1−xS@PCNWs/rGO) is synthesized through a facile assembly and sulfuration strategy. The resultant hybrid paper exhibits high flexibility and structural stability. The multidimensional paper architecture possesses several advantages, including rendering an efficient electron/ion transport network, buffering the volume expansion of Fe1−xS nanoparticles, mitigating the dissolution of polysulfides, and enabling superior kinetics toward efficient sodium storage. When evaluated as a self‐supporting anode for SIBs, the Fe1−xS@PCNWs/rGO paper electrode exhibits remarkable reversible capacities of 573–89 mAh g−1 over 100 consecutive cycles at 0.1 A g−1 with areal mass loadings of 0.9–11.2 mg cm−2 and high volumetric capacities of 424–180 mAh cm−3 in the current density range of 0.2–5 A g−1. More competitively, a SIB based on this flexible Fe1−xS@PCNWs/rGO anode demonstrates outstanding electrochemical properties, thus highlighting its enormous potential in versatile flexible and wearable applications.

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.
