“…79 The two commonly used types of organic solvents and electrolytes in SIBs include carbonate-based electrolytes (CBEs) and ether-based electrolytes (EBEs). At present, most of the reported BMO anode materials employed CBEs, while only very few BMO anode materials such as Sn/ Sb@Sb 2 SnO 5 @PCF, 80 Mn 2 V 2 O 7 , 81 and CoV 2 O 6 -rGO 82 adopted the EBEs in SIBs.…”

“…The excellent electrochemical performance can be attributed to the porous structure of Zn 3 V 3 O 3 and the modification of NC. Furthermore, due to the high theoretical capacity and diverse oxidation states of manganese (Figure 12c,d), Zheng et al 81 synthesized micrometer-sized single crystals β-phase Mn 2 V 2 O 7 by adjusting the amount of urea using hydrothermal and calcination methods (Figure 12e−g). The products were classified into three major categories based on the molar ratio of urea to manganese source, namely Mn 2 V 2 O 7 -1.4, Mn 2 V 2 O 7 -1.6, and Mn 2 V 2 O 7 -1.8.…”

“…In addition, the coupling between vanadium and other metallic elements forms metallic vanadates with enhanced ionic conductivity and increased reversible capacity as summarized in Table . Furthermore, the small volume change during Na + insertion/extraction in V-based BMOs and their ability to maintain high rate even at micrometer scale are particularly beneficial to their practical applications in SIBs …”

Compared with the bare β-NaVO 3 electrode, β-NaVO 3 /Gr could provide a reversible discharge capacity of 60 mAh g −1 at 0.5 A g −1 and the discharge capacity remained at 50 mAh g −1 after 400 cycles.…”

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.
