“…Apart from the alkali metal vanadates, alkali earth metal vanadates and transition metal vanadates, some others not belonging to these three categories were also successively reported recently, such as ammonium vanadates and AlV 3 O 9 , which further indicate the plentiful family members of the vanadates. As an example, NH 4 V 4 O 10 has recently been reported as a high‐capacity cathode for both MIBs and CIBs, respectively. Even though limited works about these phases for emerging electrochemical energy storage, they provide more opportunities in the future.…”

The emerging electrochemical energy storage systems beyond Li‐ion batteries, including Na/K/Mg/Ca/Zn/Al‐ion batteries, attract extensive interest as the development of Li‐ion batteries is seriously hindered by the scarce lithium resources. During the past years, large amounts of studies have focused on the investigation of various electrode materials toward emerging metal‐ion batteries to realize high energy density, high power density, and a long cycle life. In particular, vanadium‐based nanomaterials have received great attention. Vanadium‐based compounds have a big family with different structures, chemical compositions, and electrochemical properties, which provide huge possibilities for the development of emerging electrochemical energy storage. In this review, a comprehensive overview of the recent progresses of promising vanadium‐based nanomaterials for emerging metal‐ion batteries is presented. The vanadium‐based materials are classified into four groups: vanadium oxides, vanadates, vanadium phosphates, and oxygen‐free vanadium‐based compounds. The structures, electrochemical properties, and modification strategies are discussed. The structure–performance relationships and charge storage mechanisms are focused on. Finally, the perspectives about future directions of vanadium‐based nanomaterials for emerging energy storage devices are proposed. This review will provide comprehensive knowledge of vanadium‐based nanomaterials and shed light on their potential applications in emerging energy storage.

The successful reversible storage of Li + ( r Li + = 0.74 Å) [39][40][41], divalent Mg 2+ ( r Mg 2+ = 0.72 Å) [42], as well as larger-sized Na + ( r Na + = 1.02 Å) [43,44], and Ca 2+ ( r Ca 2+ = 1.00 Å) [45] in NH 4 V 4 O 10 as verified by theoretical calculations and experimental electrochemical measurements further predicts the feasibility of taking up Zn 2+ cations with similar size ( r Zn 2+ = 0.76 Å). To prove the above prediction, we firstly performed the first-principles calculations to evaluate the Zn 2+ ion intercalation behaviors in monoclinic NVO.…”

HIGHLIGHTS• 3D flower-like architecture assembled by NH 4 V 4 O 10 nanobelts (3D-NVO) was fabricated.• The Zn 2+ ion was intercalated into NVO cathode within the interlayer region (NH 4 V 4 O 10 ↔ Zn x NH 4 V 4 O 10 ).• The 3D-NVO cathode could deliver a large reversible capacity of 485 mAh g −1 at a current density of 100 mA g −1 for zinc-ion battery.ABSTRACT Given the advantages of being abundant in resources, environmental benign and highly safe, rechargeable zinc-ion batteries (ZIBs) enter the global spotlight for their potential utilization in large-scale energy storage. Despite their preliminary success, zinc-ion storage that is able to deliver capacity > 400 mAh g −1 remains a great challenge. Here, we demonstrate the viability of NH 4 V 4 O 10 (NVO) as high-capacity cathode that breaks through the bottleneck of ZIBs in limited capacity. The firstprinciples calculations reveal that layered NVO is a good host to provide fast Zn 2+ ions diffusion channel along its [010] direction in the interlayer space. On the other hand, to further enhance Zn 2+ ion intercalation kinetics and long-term cycling stability, a three-dimensional (3D) flower-like architecture that is self-assembled by NVO nanobelts (3D-NVO) is rationally designed and fabricated through a microwave-assisted hydrothermal c b NH 4 Zn 2+ Zn 2+ + 700 550 400 250 100 Discharge Charge Coulombic efficiency 0 1 0 2 0 Cycle number 30 40 50 Coulombic efficiency (%) 100 80 60 40 20 0 485 mAh g −1 Capacity (mAh g −1 )method. As a result, such 3D-NVO cathode possesses high capacity (485 mAh g −1 ) and superior long-term cycling performance (3000 times) at 10 A g −1 (~ 50 s to full discharge/charge). Additionally, based on the excellent 3D-NVO cathode, a quasi-solid-state ZIB with capacity of 378 mAh g −1 is developed.

“…For example, Prussian blue analgues, layered transition metal oxides and Van der Waals-bound layered transition metal sul des featured with large tunnel structure or interlayer spacings have been reported as good cathodes, while tin, graphite carbon microbeads (MCMBs), and atitivated carbon cloth served as the anodes. [10][11][12][13][14][15][16] For example, MnFe(CN) 6 //calciated-Sn battery held a capacity of ~50 mAh g -1 (based on the weight of the cathode) at 0-4 V after 30 cycles through a Ca 2+ /Na + hybrid intercalation mechanism. 10 A reversible capacity of ~ 75 mAh g -1 due to Ca 2+ insertion/extraction at 0.01-2V stably persisting for 100 cycles was reported for Na-doped ammonium vanadium oxide (NH 4 V 4 O 10 ) cathode and Ni-based framework anode system.…”

Calcium metal battery as one of the promising alternatives beyond Li-metal technology is challenged by the lack of suitable cathodes with considerable energy performance, and stable Ca anode of long-term stability and lower polorization potentials for Ca-plating/stripping. Here, by recycling cellulose waste paper of wide sources in our daily life, we develop feasible cathodes for Ca-metal batteries of good high-voltage and wide-window-voltage adaptability (0.005-4.9 V vs. Ca/Ca2+), except for considerable energy performance (~517.5 Wh kg-1 at 0.1 A g-1). Meanwhile, through tailorable Ca-plating/stripping potentials (∆V= ~0.65 V) induced by electrolyte modification, proof-of-concept Ca-metal batteries not only delivered enhanced storage capability (101 mAh g-1 vs. 51 mAh g-1 at 0.1 A g-1 in the window voltage of 2.0-4.7 V ) and cycling stability (~77% capacity retention for 100 cycles), but also simutaneously held high output average working voltage of ~3.2V.
