Antimony (Sb) is regarded as a promising anode material for sodium ion batteries (SIBs) on account of its high theoretical specific capacity (∼660 mAh g–1) and low cost. However, the large volume expansion (∼390%) during charging has inhibited its practical application. Herein, hexagonal Sb nanocrystals encapsulated by P/N-co-doped carbon nanofibers (Sb@P-N/C) were prepared using a low-cost but mass-produced electrospinning method. The as-prepared Sb@P-N/C, used as anode material for SIBs, exhibits unexpected cycling stability and rate capability, with 500.1 mAh g–1 at 50 mA g–1 after 200 cycles and 295.6 mAh g–1 at 500 mA g–1 after 400 cycles. Especially, the full battery fabricated by Na (Ni1/3Fe1/3Mn1/3) O2 || Sb@P-N/C possesses a reversible specific capacity of 66.8 mAh g–1 at 50 mA g–1 over 60 cycles. This simple and low-cost fabrication technology combined with unique crystal morphology offers new strategies for the advancement of sodium ion batteries (SIBs) in energy storage and electrical transportation.

“…[31][32][33] Besides, the low electrical conductivity stemming from the intrinsic indirect band-gap semiconductor nature of BiOX ineluctably leads to undesirable electrochemical performance of inferior rate capability and poor cycling stability. [34][35][36][37][38] Although recent carbon-hybridization of the BiOCl surface can improve the electrical conductivity and mitigate the structural collapse to some extent, a uniform nanoheterostructured construction is rather difficult via an ordinary method, which tends to cause the constructed electric field destruction within the interfacial region and increases contact resistance during potassiation/depotassiation processes. Furthermore, the developed heterostructure with interior electric field induced by phase boundaries is susceptible to both the volume change and concomitant mechanical strain.…”

Potassium ion batteries (PIBs) have attracted enormous attention due to their low cost and high abundance of potassium resources. Here, self‐hybridized BiOBr0.5I0.5 with a flower‐like structure composed of 2D nanosheets is assembled and used as PIBs anode. According to the systematic theoretical calculations, the unbalanced charge distribution between Br and I atoms induces an intensified internal electric field and a wide van der Waals gap; while the decreasing of electron polarons caused by the hybridized structure improves the stability and electronic conductivity of the system. Moreover, the K+ ion uptake induces an energetic evolution in polaronic states in the BiOBr0.5I0.5 crystal skeleton, whereby the dynamic K+ ion‐halogen atoms correlation in situ forms hole‐like polarons, which substantially promotes K+ ion diffusion kinetics and the corresponding reaction kinetics during charge/discharge processes, imparting significant implications for the design of high‐performance energy storage electrode materials by engineering the interface interaction and electronic structure. Therefore, with this atomic orbital self‐hybridized structure, the K+ ion diffusion kinetics and the corresponding reaction kinetics during the charge/discharge process are both enhanced remarkably, thus enabling a high electrochemical performance of 155 mAh g−1 at 1000 mA g−1 over 4000 cycles in PIBs with the BiOBr0.5I0.5 as the anode.
