Sodium ion batteries (SIBs) are considered as the ideal candidates for the next generation of electrochemical energy storage devices. The major challenges of anode lie in poor cycling stability and the sluggish kinetics attributed to the inherent large Na+ size. In this work, Bi nanosphere encapsulated in N‐doped carbon nanowires (Bi@N‐C) is assembled by facile electrospinning and carbonization. N‐doped carbon mitigates the structure stress/strain during alloying/dealloying, optimizes the ionic/electronic diffusion, and provides fast electron transfer and structural stability. Due to the excellent structure, Bi@N‐C shows excellent Na storage performance in SIBs in terms of good cycling stability and rate capacity in half cells and full cells. The fundamental mechanism of the outstanding electrochemical performance of Bi@N‐C has been demonstrated through synchrotron in‐situ XRD, atomic force microscopy, ex‐situ scanning electron microscopy (SEM) and density functional theory (DFT) calculation. Importantly, a deeper understanding of the underlying reasons of the performance improvement is elucidated, which is vital for providing the theoretical basis for application of SIBs.

Sodium-ion batteries (SIBs) are close to commercialization. Although alloying anodes have potential use in next-generation SIB anodes, their limitations of low capacities and colossal volume expansions must be resolved. Traditional approaches involving structural and compositional tunings have not been able to break these lofty barriers. This review is devoted to recent progress in research on alloy-based SIB anodes comprising Sn, Sb, P, Ge, and Si. The current level of understanding, challenges, modifications, optimizations employed up to date, and shortfalls faced by alloying anodes are also described. A detailed future outlook is proposed, focusing on advanced nanomaterial tailoring methods and component modifications in SIB fabrication. Utilizing the latest state-of-the-art characterization techniques, including ex-situ and operando characterization tools, can help us better understand the (de)sodiation mechanism and accompanying capacity fading pathways to pave the way for next-generation SIBs with alloying anode materials.
