“…[ 130 ] It was demonstrated that during discharge/charge of Zn/V 2 O 5 hybrid‐ion battery, a reversible coinsertion/extraction of Li + and Zn 2+ ions into/from the interlayer of V 2 O 5 structure occurred as confirmed by spectroscopy analysis. [ 130 ] Similarly, Batyrbekuly et al [ 131 ] investigated Zn//3 m Li 2 SO 4 + 4 m ZnSO 4 //V 2 O 5 hybrid‐ion battery and demonstrated that this battery involves mainly the insertion/extraction of Li + ions in layered V 2 O 5 and dissolution/precipitation of zinc in the negative electrode. This battery delivered reversible specific capacities of 136 and 125 mAh g −1 at 15 mA g −1 (C/20) and 60 mA g −1 (C/5), respectively.…”

“…In a similar manner, hybrid‐ion battery (Zn/V 2 O 5 ) was investigated by Batyrbekuly et al with their original concept of binary Li + /Zn 2+ electrolytes. [ 131 ] The binary electrolyte consists of Li 2 SO 4 and ZnSO 4 , which fully dissociates into their respective ion compositions. The unique mechanism of this hybrid ZIB involves the Li + insertion/extraction in the positive side, whereas Zn dissolution/precipitation occurs in the other (negative).…”

Aqueous zinc‐ion batteries (AZIBs) are promising candidates for grid‐scale energy‐storage systems, which are essential for maintaining and distributing energy generated from various sources. In contrast to current commercial lithium‐ion batteries (LIBs), AZIBs offer advantages such as, but not limited to, high safety, low cost, and fast kinetics. Zn intercalation material serves as the key element for the suitability of Zn‐ion batteries (ZIBs) for grid and stationary applications. Different materials are tested as cathode materials for ZIBs, including manganese oxides and vanadium oxides. MnO2‐ and V2O5‐based cathodes, in particular, seem compatible with ZIBs, with the potential to perform better than existing batteries in the market. Due to the fast and facile (de)intercalation‐type storage mechanism of Zn2+ ions, layered electrode materials generally have a more stable structure during battery charge and discharge cycles. Materials with large interlayer spacing are expected to exhibit good electrochemical performance, thereby favoring hydrated and cation‐intercalated materials in the development of AZIBs cathodes. Herein, an overview is provided on the synthesis, morphology, and electrochemical performance of various MnO2‐ and V2O5‐based cathode materials in AZIB, as well as the challenges that must be overcome to reach the commercialization of AZIBs.

“…Interestingly, in addition to the co‐insertion of Zn 2+ /H + ions, the employ of mixed electrolyte can achieve the co‐insertion of bimetal ions. For example, Batyrbekuly et al assembled a Zn/V 2 O 5 battery with a mixed electrolyte of 3 m Li 2 SO 4 and 4 m ZnSO 4 , [ 72 ] thereby realizing the co‐insertion of Zn 2+ /Li + . The Zn/V 2 O 5 hybrid system has high structural stability and rate performance.…”

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...

Aqueous rechargeable zinc batteries are getting increasing attention for large-scale energy storage owing to their advantages in terms of cost, environmental friendliness and safety. Here, the layered puckered γ'-V2O5 polymorph with a porous morphology is firstly introduced as cathode for an aqueous zinc battery system in a binary Zn 2+ /Li + electrolyte. The Zn||γ'-V2O5 cell delivers high capacities of 240 and 190 mAh g -1 at current densities of 29 and 147 mA g -1 , respectively, and remarkable cycling stability in the 1.6 V -0.7 V voltage window (97% retention after 100 cycles at 0.15 A g -1 ). The detailed structural evolution during first discharge-charge and subsequent cycling is investigated using X-ray diffraction and Raman spectroscopy. We demonstrate a reaction mechanism based on a selective Li insertion in the 1.6 V -1 V voltage range.It involves a reversible exchange of 0.8 Li + in γ'-V2O5 and the same structural response as the one reported in lithiated organic electrolyte. However, in the extended 1.6 V -0.7 V voltage range, this work puts forward a concomitant and gradual phase transformation from γ'-V2O5 to zinc pyrovanadate Zn3V2O7(OH)2.2H2O (ZVO) during cycling. Such mechanism involving the in-situ formation of ZVO, known as an efficient Zn and Li intercalation material, explains the high electrochemical performance here reported for the Zn||γ'-V2O5 cell. This work highlights the peculiar layered-puckered γ'-V2O5 polymorph outperforms the conventional α-V2O5 with a huge improvement of capacity of 240 mAh g -1 vs 80 mAh g -1 in the same electrolyte and voltage window.
