Antimony-based materials are promising anode candidates for sodium-ion batteries (NIBs) due to their high theoretical capacity of 660 mAh g -1 (Na 3 Sb). In fact, antimony-based alloying and conversion-alloying electrodes exhibit high capacity and cycling stability, with newly developed strategies to overcome the common problem of volume expansion, all leading to renewed interest in antimony-based NIB materials. In this review, we discuss the performance of antimony-based materials for energy storage and conversion devices such as NIBs, Na-ion fuel cells, sea-water batteries, and Na-air batteries. This review also tackles common issues in NIBs that employ antimony-based materials (e.g., Sb-carbon composite and Sb 2 X 3 (X -O, and S), as well as several strategies that can be adopted to address these limitations.

The Dual Capacity Contribution Mechanism of SnSb‐Anchored Nitrogen‐Doped 3D Reduced Graphene Oxide Enhances the Performance of Sodium‐Ion Batteries

Nanoscale SnSb alloys exhibit lower expansion rates and outstanding electrochemical properties, owing to the synergy between Sn and Sb for anode materials of sodium-ion batteries. However, nanomaterials with a high surface energy tend to aggregate and form larger secondary particles, limiting their further application. Herein, SnSb nanoparticles are prepared and distributed in three-dimensional networks of N-doped reduced graphene oxide (3D-rNGO), which plays a crucial role in inhibiting the agglomeration of SnSb nanoparticles, thereby promoting the capacitive contribution of surface drive. More importantly, the three-dimensional structure has a high specific surface area and the active region introduced by N doping can contact and adsorb more sodium ions as part of the electrochemical behavior, making the SnSb/3D-rNGO anode not only contribute capacity through a diffusion process, but also provide a capacitive contribution through a surface-driven mechanism. The results of the electrochemical analysis showed that SnSb/3D-rNGO, as the anode of a sodium-ion battery, exhibits a high specific capacity of 1169.6 mAh g À 1 , a reversible capacity of 55 % at 0.1 C, and maintains a capacity of 479.3 mAh g À 1 after 200 cycles. It is suitable for energy storage precisely because of the double capacity contribution mechanism.

It is essential to stabilize the surface of P2 layered cathode materials at high cut-off voltages (> 4.3 V) in order to construct high-energy sodium ion batteries (SIB) that are promising for commercial application. When the voltage exceeds 4.3 V, large volume changes due to phase transitions and active species dissolution affect the structural stability of high voltage cathodes. In this study, we report a novel method of enhancing the electrochemical cycling performance of P2-type Na 2/3 (Mn 0.54 Ni 0.13 Co 0.13 )O 2 (NNMC) materials through ionconductive polyimide (PI) encapsulation. The electrochemical performance of ultrathin PI coated NNMC (PI-NNMC) is one of the best reported in the literature among layered cathodes in terms of cyclic stability (82 % after 100 cycles at 0.16 A g -1 ) at a high voltage range between 2 and 4.5 V, compared to the pristine (46 %) and Al 2 O 3 -coated NNMC (70 %). At high current (5 C), the NNMC-PI electrode demonstrates superior cyclability by retaining 70 % of its capacity after 500 cycles. The ultrathin PI layer possesses excellent surface protection, high ionic conductivity (vs Al 2 O 3 coating) and facile ion transport, thus enabling a fast and durable redox electrochemistry in NNMC materials for high-performance sodium storage above 4.3 V.
