“…The initial discharge and charge specific capacity of SnS-C/NS@CNF electrodes are as high as 1328.1 and 950.7 mAh/g, respectively, which implies that the initial Coulombic efficiency (ICE) is 71.6%. The largely irreversible capacity loss after the initial cycle is mainly due to the formation of the SEI film, the surface impurities, and the decomposition of the electrolyte. − There is no obvious change in the curves of SnS-C/NS@CNFs, Sn-C/N@CNFs (Figure S7a), and SnS/NS@CNFs (Figure S7b) after the initial cycle, indicating the stability and small polarization of the electrode material. As for cycle stability, SnS-C/NS@CNFs exhibit the best cycle performance compared to Sn-C/N@CNFs and SnS/NS@CNFs.…”

The significant capacity loss and pulverization caused by the dramatic increase in volume of Sn-based anodes during redox reactions severely limit their practical application in lithium-ion batteries. Herein, with the ultralong cycle life and high capacity Sn-based compounds (SnS-C/NS@CNFs), a self-supporting anode was prepared by electrospinning followed by the calcination scheme, which is a superb material for lithium storage since the buffer matrix reduces the volume expansion of Sn. In this strategy, SnS nanoparticles are scattered into a porous carbon framework using Sn-MOFs as a pore-forming template, which allows for easier extraction–insertion of Li-ions due to their inherent layered structure. Moreover, the nitrogen and S-doped carbon nanofibers not only serve as a barrier to impede the aggregation and volume expansion of SnS during cycling but also act as electrical pathways to enhance the conductivity of the electrodes. Having profited from the desirable nanostructures, the flexible three-dimensional cross-linked nanofibers were straightly used as a self-supporting anode for LIBs, displaying ultralong cycle life (455.8 mAh/g after 1000 cycles at 1 A/g) and exceptional rate performance (481 mAh/g at 2 A/g). This work offers a reliable and efficient method for fabricating flexible self-standing and durable electrodes.

“…For the sodium salts, sodium perchlorate (NaClO 4 ), sodium hexafluorophosphate (NaPF 6 ), sodium tetrafluoroborate (NaBF 4 ), and sodium trifluoromethanesulfonate (NaCF 3 SO 3 ) are the most commonly used ones in BMOs (Figure 7a). 83 Surendran et al 84 synthesized BiFeO 3 nanoparticles through a sol−gel method. The cycling stability of BiFeO 3 was then optimized by changing the electrolyte composition.…”

Sodium-ion batteries (SIBs) are considered as an alternative to and even replacement of lithium-ion batteries in the near future in order to address the energy crisis and scarcity of lithium resources due to the wide distribution and abundance of sodium resources on the earth. The exploration and development of high-performance anode materials are critical to the practical applications of advanced SIBs. Among various anode materials, bimetallic oxides (BMOs) have attracted special research attention because of their abundance, easy access, rich redox reactions, enhanced capacity and satisfactory cycling stability. Although many BMO anode materials have been reported as anode materials in SIBs, very limited studies summarized the progress and prospect of BMOs in practical applications of SIBs. In this review, recent progress and challenges of BMO anode materials for SIBs have been comprehensively summarized and discussed. First, the preparation methods and sodium storage mechanisms of BMOs are discussed. Then, the challenges, optimization strategies, and sodium storage performance of BMO anode materials have been reviewed and summarized. Finally, the prospects and future research directions of BMOs in SIBs have been proposed. This review aims to provide insight into the efficient design and optimization of BMO anode materials for high-performance SIBs.

“…The conformation and properties of SEI are also closely related to the choice of electrolyte salt. Wen et al [102] clarified the correlation between NaOTf/NaClO 4 salts and the morphology and properties of SEI formed on the carbon matrix composite anode. Consequently, a thin, dense, and uniform SEI contained rich sulfur compounds that came from the decomposition of NaOTf electrolyte.…”

Carbon‐based materials have emerged as promising anodes for sodium‐ion batteries (SIBs) due to the advantages of cost‐effectiveness and renewability, whereas the unsatisfactory performance has hampered the commercialization of SIBs. During the past decades, tremendous efforts have been put to enhance the electrochemical performance of SIBs from the perspective of improving the compatibility of electrolytes and electrodes. Hence, a systematic summary of the strategies for tuning electrolytes between hard carbon, graphite, and other structural carbon anodes of SIBs is provided. The formulations and properties of electrolytes with solvents, salts, and additives added, which are closely related to the formation of solid electrolyte interface (SEI) as well as crucial to the reversible capacity, rate capability, and cycling stability of carbon‐based anodes, are comprehensively presented. This review is anticipated to provide guidance in future rational tailoring of electrolytes with carbon‐based anodes for sodium‐ion batteries.
