“…Figure e shows the high-resolution XPS spectra in the Sb 3d region, where two peaks are observed at the binding energies of 530.4 and 539.3 eV, assigning to the presence of Sb 4+ on the surface . The bonding energy of the Sb 3d peak in the NiFeSbP (530.4 eV) coating is lower than those of NiSbP (531.4 eV) and NiSb (531.0 eV) coatings, which suggests the enhancing electron transfer between Sb and other elements as well as increased tendency of the NiFeSbP coating to adsorb or release of the intermediate components in the HER or OER reactions .…”

Designing high-performance electrocatalysts for water splitting and urea-assisted electrolysis is of great significance in the hydrogen production industry. Herein, a hierarchical flower-like NiFeSbP electrocatalyst with different Ni/Fe ratios was fabricated on a graphite bar (GB) through a one-step electrodeposition method. By optimizing and regulating the ratios of Ni and Fe in the composition, the NiFeSbP electrocatalyst exhibited excellent hydrogen evolution reaction (HER), oxygen evolution reaction (OER), and urea oxidation reaction (UOR) activities with overpotentials of 143, 323, and 272 mV at 100 mA·cm–2, sequentially, and also demonstrated longevity for over 100 h in an alkaline solution. More impressively, a symmetrical electrolyzer using NiFeSbP/GB as both the anode and cathode to afford a current density of 10 mA·cm–2 needs 1.72 V for overall water splitting and 1.54 V for urea-assisted electrolysis. The superior catalytic performances of the NiFeSbP/GB catalyst in the urea-added water electrolysis mainly benefit from the synergistic effect between tricomponent metal catalytic centers (Ni, Fe, and Sb) and P atoms, which modulates the chemical and electronic structure of the catalyst. This work opens up new prospects for the rational design of versatile and stable UOR electrocatalysts for hydrogen generation in an efficient manner.

“…The advantage of Sb-based alloys is that the introduction of suitable phases can change the electrochemical properties of Sb and alleviate its volume expansion during the process of sodium storage. In addition, the phase with sodium storage characteristics better cooperates with Sb [117][118][119][120]. Generally, many types of binary Sb-based intermetallic compounds, and even ternary Sb-based alloys, can be synthesized based on the alloy phase diagram.…”

The development of sodium-ion (SIBs) and potassium-ion batteries (PIBs) has increased rapidly because of the abundant resources and cost-effectiveness of Na and K. Antimony (Sb) plays an important role in SIBs and PIBs because of its high theoretical capacity, proper working voltage, and low cost. However, Sb-based anodes have the drawbacks of large volume changes and weak charge transfer during the charge and discharge processes, thus leading to poor cycling and rapid capacity decay. To address such drawbacks, many strategies and a variety of Sb-based materials have been developed in recent years. This review systematically introduces the recent research progress of a variety of Sb-based anodes for SIBs and PIBs from the perspective of composition selection, preparation technologies, structural characteristics, and energy storage behaviors. Moreover, corresponding examples are presented to illustrate the advantages or disadvantages of these anodes. Finally, we summarize the challenges of the development of Sb-based materials for Na/K-ion batteries and propose potential research directions for their further development.

“…Owing to the low cost and wide distribution of Na, sodium-ion batteries (SIBs) have emerged as viable alternatives to lithium-ion batteries for grid-scale energy storage. − To date, one of the major obstacles hampering the practical application of SIBs is the lack of appropriate anode materials. , To address this challenge, many anode materials, mainly including intercalation (e.g., carbonaceous and Ti-based materials), − conversion (e.g., transition metal oxide and transition metal sulfide), − and alloying compounds (e.g., Sn, Bi, Sb and P), − have been developed. Among them, alloying compounds featuring a high theoretical capacity and relatively low sodiation potential have been regarded as promising anode materials for SIBs .…”

Yolk–Shell Sb@Void@Graphdiyne Nanoboxes for High-Rate and Long Cycle Life Sodium-Ion Batteries

Antimony (Sb) has been pursued as a promising anode material for sodium-ion batteries (SIBs). However, it suffers from severe volume expansion during the sodiation–desodiation process. Encapsulating Sb into a carbon matrix can effectively buffer the volume change of Sb. However, the sluggish Na+ diffusion kinetics in traditional carbon shells is still a bottleneck for achieving high-rate performance in Sb/C composite materials. Here we design and synthesize a yolk–shell Sb@Void@graphdiyne (GDY) nanobox (Sb@Void@GDY NB) anode for high-rate and long cycle life SIBs. The intrinsic in-plane cavities in GDY shells offer three-dimensional Na+ transporting channels, enabling fast Na+ diffusion through the GDY shells. Electrochemical kinetics analyses show that the Sb@Void@GDY NBs exhibit faster Na+ transport kinetics than traditional Sb@C NBs. In situ transmission electron microscopy analysis reveals that the hollow structure and the void space between Sb and GDY successfully accommodate the volume change of Sb during cycling, and the plastic GDY shell maintains the structural integrity of NBs. Benefiting from the above structural merits, the Sb@Void@GDY NBs exhibit excellent rate capability and extraordinary cycling stability.
