“…The results revealed that cathodes with high mass loading exhibited poor rate performance, which demonstrated that thick cathodes restricted the pseudo-Zn-air reaction and the diffusion of Zn 2 + . To alleviate the severe capacity decay of V x O y electrodes, Ru et al [94] devised an innovative method to prepare Recently, Wang et al [95] got a new approach based on the ability to substantially increase the electrochemical capacity of aqueous Zn/V 5 O 12 • 6H 2 O cells by adding a small amount of platinum (Pt, 1.5 wt.%). Given their previous work, [93] the electrochemical performance was enhanced by adjusting the quantities of oxygen-containing functional groups on the GO surface.…”

The rapid depletion of lithium resources and the increasing demand for electrical energy storage have stimulated the pursuit of emerging electrochemical energy storage. Aqueous zinc ion batteries (ZIBs) are highly sought after for their low cost, high safety, and increased environmental compatibility. However, the search for suitable cathode materials is still tricky for a wide range of researchers. Vanadium oxides (V x O y ), with their abundant vanadium valence, easily deformable VÀ O polyhedrons, and tunable chemical compositions, are of significant advantage in developing emerging materials. This work provides a detailed review of different V x O y for the application in aqueous ZIBs. The current problems and optimization strategies of V x O y cathode materials are systematically discussed. Finally, the current challenges and possible directions for future research of V x O y cathode materials in aqueous ZIBs are presented.

“…. [103] Owing to the buffering effect of inert Zn(OH) 2 •0.5H 2 O, repeated insertion/extraction of Zn 2+ can be tolerated continuously, thereby relieving serious volume changes. Different from the reported lamellar vanadium oxides, Li et al synthesized novel heterogeneous vanadium oxide nanowires with a V 2 O 5 •nH 2 O shell and a V 3 O 7 •H 2 O nucleus, and called h-VOW.…”

development, but these energy sources have geographical limitations and instability, so it is difficult to achieve a wide range of applications. As an important part of sustainable energy development, electrochemical energy storage has become an area of active research in recent decades. [7-10] In the current energy market, lithium ion batteries (LIBs) are dominant in the automobile, medical equipment, and portable wearable device industries, among others, which can be attributed to their outstanding energy density and environmental protection performance. [11,12] However, the use of organic solvent-based electrolytes may raise safety issues and increase costs. [13-19] Therefore, the creation of an efficient battery system is very important. Compared with nonaqueous batteries, aqueous rechargeable batteries have the characteristics of low cost, nontoxicity, and incombustibility, and are more economically competitive than lithium technology in terms of largescale deployment. [20-22] Therefore, the most important task at present is to develop an ideal battery device with low cost, acceptable safety, long cycle performance, and environmental friendliness as a substitute for LIBs. [23-25] For the past few years, ion batteries with polyvalent metals as the negative electrodes have attracted much attention. Polyvalent cations (Zn 2+ , Mg 2+ , Al 3+) transfer twice or even three times as many electrons into the main material as monovalent cations (Li + , Na +), and each polyvalent positive ion can be inserted into the main compound. [26-32] Theoretically, the capacity of the host material depends on the number of transferred electrons coexisting with the intercalated ions, such that multivalent positive ions have higher weight capacity and energy density. [33] Notably, the element zinc (Zn) has become a common choice for a negative electrode material, owing to its ample sources, low price, low redox potential (−0.76 V vs standard hydrogen electrode), and high surface capacity. [34,35] The mixture of aqueous solution and/or aqueous solution and organic-based electrolyte has emerged as a new research field. Therefore, aqueous zinc ion batteries (ZIBs) have been widely considered for their advantages of high safety, low price, ecological friendliness, and high theoretical capacity. [36] Typically, aqueous ZIBs consist of a Zn metal negative electrode, an aqueous electrolyte that accounts for a majority of the battery material, and a positive electrode containing Zn 2+ ions. [37] A survey has revealed that the conventional With the increasing dependence on high power equipment, there is an urgent need to develop advanced and sustainable energy systems. As one of the main energy storage devices, battery research should make great efforts to implement the sustainable development strategies on ecological, clean and environmentally friendly energy. Currently, aqueous zinc ion batteries (ZIBs) have gained much attention owing to their cheapness, abundant resources, high safety, and ecological friendliness. Nevertheless, ZIBs als...

Rechargeable aqueous zinc‐ion batteries (AZIBs) are recognized as one of the most competitive next generation energy storage systems due to the high theoretical capacity (820 mAh g−1), abundant reserves, low expense, and environmental friendliness. However, in comparison to that monovalent ion secondary battery, the multivalent ion rechargeable battery faces larger metal ion sizes and higher charge/discharge number in the electrochemical reaction process, thereby suffering from larger steric resistance and the electrostatic repulsion in the intercalation–deintercalation process. At present, a great deal of research has shown that the guest ion pre‐embedded host structured cathodes can effectively alleviate the above problems and improve the comprehensive performance of aqueous zinc ion battery. In this review, the development of vanadium oxide ion‐intercalated cathode materials in AZIBs is reviewed, mainly including MXV2O5∙nH2O, MXV3O8∙nH2O, MXV6O13∙nH2O, MXV6O16∙nH2O, and MXV10O25∙nH2O type materials. The reaction mechanisms and electrochemical performance of these materials are described, and the future research directions are prospected. It is expected to provide fundamental and engineering guidance for the development of high performance AZIBs cathode materials.
