“…9 The layered character of V 2 O 5 and the high redox potential of V 5+ make it an interesting and versatile host material for many guest species and for batteries based on intercalation of ions such as lithium, sodium, magnesium and aluminium. [11][12][13] In addition, vanadium pentoxide gels are very sensitive to some reduction of vanadium ions (weak mixed V 5+ -V 4+ character) and its content in V 4+ is related to the water content (dehydratation leads to some reduction of vanadium). 10 The xerogel (xero-V 2 O 5 ) consists of V 2 O 5 bilayers with water between them and it is a Brønsted acid.…”

“…It is worth to note that xero-V 2 O 5 adsorbs water at the oxide-air interface and that, according to the layer structure of V 2 O 5 , water absorption may be described as an intercalation process. [10][11][12][13][14][15] According to the literature, 14 15 Surprisingly, in contrast to lithium and magnesium batteries, the role of water molecules in the aluminium intercalation into V 2 O 5 has received little attention. Thus, the intercalated water can play an important role in the electrochemistry of V 2 O 5 .…”

a Rechargeable batteries based on the intercalation of aluminium ions may be competitive against lithium-ion batteries, but their development and comprehension are full of difficulties. The charge/discharge processes are particularly complex in aqueous electrolyte solutions. The electrochemical behaviour of orthorhombic V2O5, obtained from xerogel, in aluminium cell is studied here by using electrochemical cycling, impedance spectroscopy, XRD and XPS results. After electrochemical intercalation of aluminium, the resulting (Al 3+ )x/3[(V 4+ )x,(V 5+ )2-x]O5.nH2O is XRD-amorphous at approximately x=1.5. The reversible capacity is ca. 120 mAh g -1 (equivalent to Al0.27V2O5). The loss of crystallinity induced by the electrochemical intercalation enhances the chemical exchange between the electrode material and the electrolyte solution. In the presence of acidic water solution, besides the faradic electrochemical process driven by the electrical current, aluminium, proton and water also can be intercalated into V2O5 by chemical reactions or ion exchange.

In comparison with anatase, 2 the voltage of V 2 O 5 is higher, and discharge: solid symbols charge: open symbols (B)

In recent years, noticeable progress is achieved regarding alkaline rechargeable batteries (ARBs). Due to their merits of safety and low cost, ARBs are considered promising energy storage sources for large-scale grid energy storage, electric vehicles, and hybrid electric vehicles, as well as wearable and portable devices. While previous reviews have focused on specific topics associated with ARBs, providing a comprehensive review on rechargeable alkaline batteries is both timely and worthwhile. In this review, the recent progress in ARBs is summarized and the strategies underlying rational electrode designs for cathodes and anodes are highlighted, as well as their applications in full cells including flexible batteries. This review may pave the way for further designs of high-performance alkaline batteries. and a LiMn 2 O 4 cathode in 1994. [10] However, the electrolyzation of H 2 O limits the operating voltage window of ARABs, which are stable within ≈1.23 V. Furthermore, the electrode materials should be selected so that they avoid the electrolysis of H 2 O and maintain chemical stability in H 2 O. [3a] However, the preferred LIB cathodes, such as LiCoO 2 , LiMn 2 O 4 , and LiFePO 4 , which display a reversible capacity of 140, [11] 120, [12] and 170 mAh g −1 , [13] respectively, exhibit narrow working potentials and high stability in aqueous solutions but can take part in one-electron reactions at most. In addition, promising anode materials, such as VO 2 , [14] V 2 O 5 , [15] and H 2 V 3 O 8 , [16] possess the theoretical capacity or show the highest reversible capacity of only 161.6, 200, and 234 mAh g −1 , respectively, [3a] thereby leading to a full cell with a low energy density under the limited operating voltage window in aqueous electrolytes. Although the so-called "water-in-salt" electrolyte and its many variations can enable aqueous batteries with an electrochemical stability window of >3.0 V and an energy density of 200 Wh kg −1 , respectively, the ultrahighly concentrated electrolyte makes the cost too high for practical applications. [17] Since the early 20th century, alkaline rechargeable batteries (ARBs) based on nickel-iron (Ni-Fe) and nickel-cadmium (Ni-Cd) have been established and developed by Jüngner and Edison. [18] These batteries, which use alkaline solution as electrolytes, undergo an entirely different storage mechanism from ARABs and involve H + insertion/extraction and conversion processes from the alkali-metal ion insertion/extraction. Take the reaction mechanism of Ni-Fe batteries as an example

“…These studies revealed a screening effect of water on Mg 2+ during the intercalation process. Later, many researchers investigated the intercalation behavior of polyvalent ions in various electrode materials, including aerogels [ 23 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 ]. In 1998, for the first time, Le et al [ 29 ] investigated the intercalation of Al 3+ and Mg 2+ in V 2 O 5 aerogels, and they also reported the advantage of water molecules in the V 2 O 5 aerogel structures providing steric hindrance effect on intercalating Mg 2+ and thereby aiding in a good reversibility of multivalent ion insertion into V 2 O 5 aerogels.…”

Rapidly growing global demand for high energy density rechargeable batteries has driven the research toward developing new chemistries and battery systems beyond Li-ion batteries. Due to the advantages of delivering more than one electron and giving more charge capacity, the multivalent systems have gained considerable attention. At the same time, affordability, ease of fabrication and safety aspects have also directed researchers to focus on aqueous electrolyte based multivalent intercalation batteries. There have been a decent number of publications disclosing capabilities and challenges of several multivalent battery systems in aqueous electrolytes, and while considering an increasing interest in this area, here, we present a brief overview of their recent progress, including electrode chemistries, functionalities and challenges.
