“…Moreover, the aforementioned superior half-cell performances of 1/12-NNMF motivate us to further investigate its fullcell properties, aiming at preliminarily evaluating the practicability of the 1/12-NNMF cathode in SIB. Therefore, we built the coin-type Na-ion full cell by coupling the 1/12-NNMF cathode with an LS−Sb@G anode as we recently reported, 30 and the assembled full cell schematized in Figure 7b was written as "Sb@G//NNMF". Figure 7a exhibits the typical GCD curves of the Sb@G//NNMF full cell, in which the average voltage is 2.83 V over the working voltage range of 1.7−4.0 V. The rate profiles shown in Figure 7c further reveal the superior energy storage capability of the assembled Sb@ G//NNMF full cell.…”

“…It also showed excellent LT properties with a capacity of 84 mA h g −1 at −25 °C after 80 cycles and remarkable full-cell properties when combined with an LS−Sb@G anode. 30 All these data indicate that iron can be a good substitution element in NNMO, which serves as the best balance between the satisfactory electrochemical performance and appropriate physical properties to lead to the development of SIB.…”

As a promising cathode material of sodium-ion battery, P2-type NaNiMnO (NNMO) possesses a theoretically high capacity and working voltage to realize high energy storage density. However, it still suffers from poor cycling stability mainly incurred by the undesirable P2-O2 phase transition. Herein, the electrochemically active Fe ions are introduced into the lattice of NNMO, forming NaNiMnFe O ( x = 0, 1/24, 1/12, 1/8, 1/6) to effectively stabilize the P2-type crystalline structure. In such Fe-substituted materials, both Ni/Ni and Fe/Fe couples take part in the redox reactions, and the P2-O2 phase transition is well restrained during cycling, as verified by ex situ X-ray diffraction. As a result, the optimized NaNiMnFeO (1/12-NNMF) has a long-term cycling stability with the fading rate of 0.05% per cycle over 300 cycles at 5 C. Furthermore, the 1/12-NNMF delivers excellent rate capabilities (65 mA h g at 25 C) and superior low-temperature performance (the capacity retention of 94% at -25 °C after 80 cycles) owing to the enhanced Na diffusion upon Fe doping, which is deduced by the studies of electrode kinetics. More significantly, the 1/12-NNMF also displays remarkable sodium-ion full-cell properties when merged with an LS-Sb@G anode, thus implying the possibility of their practical application.

“…Huang et al 65 suggested a uniformly stacked layer of Sb nanosheets on graphene matrix which formed a layer-stacked Sb@graphene micro/nanocomposite (LS-Sb@G) which was recognized to be a good candidate for the NIB anode material. The LS-Sb@G active material was synthesized through a solvothermal method in a Teflon container by heating an ultrasonic treatment of a solution of SbCl 3 , graphene oxide, HCOOH and the as-obtained material was mixed with CMC, acetylene black using water as solvent (80:10:10 wt %) to prepare a slurry which was coated on a copper foil with a mass loading of 1.2-1.4 mg cm -2 .…”

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.

“…Enabling a full‐cell configuration with better electrochemical performance is a major challenge toward the commercialization of the SIB system. On the anode side, Sb and Sb/C materials have been explored recently as promising candidates because of their high reversible capacity and low cost . With a 3‐electron involved redox process, a theoretical capacity of 660 mAh/g can be realized for the Sb anode, which corresponds to the formation of Na 3 Sb.…”

Excellent structural stability, high operating voltage, and high capacity have made Na 3 V 2 (PO 4) 2 F 3 a promising cathode material for sodium-ion batteries. However, high-temperature battery performances and heat generation measurements have not been systematically reported yet. Carbon-coated Na 3 V 2 (PO 4) 2 F 3 @MWCNT (multi-walled carbon nanotube) samples are fabricated by a hydrothermal-assisted sol-gel method and the electrochemical performances are evaluated at three different temperatures (25, 45, and 55°C). The well-crystallized Na 3 V 2 (PO 4) 2 F 3 @MWCNT samples exhibit good cycling stability at both low and high temperatures; they deliver an initial discharge capacity of 120-125 mAhg À 1 at a 1 C rate with a retention of 53 % capacity after 1,400 cycles with 99 % columbic efficiency. The half-cell delivers a capacity of 100 mAhg À 1 even at a high rate of 10 C at room temperature. Furthermore, the Na 3 V 2 (PO 4) 2 F 3 @MWCNT samples show good long-term durability; the capacity loss is an average of 0.05 % per cycle at a 1 C rate at 55°C. Furthermore, ionic diffusivity and charge transfer resistance are evaluated as functions of state of charge, and they explain the high electrochemical performance of the Na 3 V 2 (PO 4) 2 F 3 @MWCNT samples. In-situ heat generation measurements reveal reversible results upon cycling owing to the high structural stability of the material. Excellent electrochemical performances are also demonstrated in the full-cell configuration with hard carbon as well as antimony Sb/C anodes.
