“…The XRD pattern of the newly formed phase is further extracted from that of VOG discharged to 0.4 V. As shown in Figure S9 (Supporting Information), the peaks located at 13.14° and 19.73° are indexed as the high-order diffraction of that at 6.53°. This phenomenon is different from the XRD results of Zn 0.25 V 2 O 5 under operando conditions, [30] in which the lattice interlayer distance decreases with Zn 2+ intercalation. For VOG, the interlayer distance increases from 10.4 to 13.5 Å upon Zn 2+ intercalation, in contrast to the previously reported lattice contraction, which we attribute to the coexistence of structural water and Zn 2+ in between V 2 O 5 bilayers.…”

“…[23][24][25][26][27][28] Recently, Pan et al demonstrated that the manganese oxide cathode goes through a chemical conversion reaction with the zinc species and H 2 O rather than the simple intercalation process, delivering a high capacity of ≈285 mA h g −1 and an operating voltage of ≈1.44 V. [29] Nazar's group developed a Zn 0.25 V 2 O 5 ·nH 2 O cathode material, which displayed a specific energy of ≈250 Wh kg −1 (based on cathode) and a high capacity of 220 mA h g −1 at 15 C (1 C = 300 mA g −1 ). [30] During cycling, the structural water in Zn 0.25 V 2 O 5 ·nH 2 O was revealed to exchange with Zn 2+ reversibly, thus resulting in good kinetics and rate performance.

Among the aqueous rechargeable batteries, Zn 2+ -based batteries exhibit a series of unique attributes for large-scale energy storage: (i) feasibility of using low-cost Zn metal anode with a high theoretical specific capacity of 819 mA h g −1 ; (ii) replacement of the traditional alkaline electrolytes by mild neutral electrolytes, mitigating the environmental disruption and recycling costs; and (iii) low redox potential of Zn/Zn 2+ (−0.76 V vs standard hydrogen electrode) and two-electron transfer mechanism during cycling responsible for the high energy density. [6,22,23] However, the zinc system also has long-standing challenges, such as the unstable cathode and anode structures in the aqueous environment. On the cathode side, the cycling stability is related to how zinc ions and the electrolyte react with the cathode materials, which is much more complex as compared to the lithium-ion systems. An initial attempt on the hexacyanoferrate system delivered a limited capacity (≈60 mA h g −1 ), although a high operation voltage of ≈1.7 V was achieved. [23][24][25][26][27][28] Recently, Pan et al. demonstrated that the manganese oxide cathode goes through a chemical conversion reaction with the zinc species and H 2 O rather than the simple intercalation process, delivering a high capacity of ≈285 mA h g −1 and an operating voltage of ≈1.44 V. [29] Nazar's group developed a Zn 0.25 V 2 O 5 ·nH 2 O cathode material, which displayed a specific energy of ≈250 Wh kg −1 (based on cathode) and a high capacity of 220 mA h g −1 at 15 C (1 C = 300 mA g −1 ). [30] During cycling, the structural water in Zn 0.25 V 2 O 5 ·nH 2 O was revealed to exchange with Zn 2+ reversibly, thus resulting in good kinetics and rate performance. Furthermore, some other studies have also suggested the importance of H 2 O in metal ion intercalation. [23,31] During cycling, the solvating H 2 O works as a charge shield for the metal ions (Al 3+ , Mg 2+ , Li + , etc.), reducing their effective charges and hence their interactions with the host frameworks. [32,33] This strategy has been investigated to enhance the capacity and rate capability of Li + , Na + , and Mg 2+ batteries. [34][35][36][37][38][39] In this paper, we present a systematic and detailed study of the role of H 2 O in bilayer V 2 O 5 ·nH 2 O (n ≥ 1) as a prototype cathode material for zinc batteries. By coupling the electrochemical measurements, thermogravimetric/differential BatteriesLarge-scale energy storage systems are critical for the integration of renewable energy and electric energy infrastructures. [1][2][3] Among numerous candidates, lithium-ion batteries with organic electrolytes are one of the most attractive options due to their high energy density [4][5][6][7][8][9][10] and mature markets. [11,12] However, for grid scale energy storage, the cost of lithium-ion batteries is still too high, [13,14] and the use of the flammable organic electrolyte in large format batteries poses a severe safety and environmental concern. [15] As an alternative, low-cost aqueous batteries wi...

Advanced energy storage devices, i.e., Li-ion battery, supercapacitor, need high electroactive metal oxide materials with stable structure during charging/ discharging cycling [1][2][3]. However, metal oxide electrode materials often suffer from low conductivity, and slow ion diffusion rate during electrochemical redox reaction. In recent years, lots of efforts are done to design nanostructured materials to enhance their function. When downsizing to nanosize, the electroactive areas of materials are increased and ion/electron diffusion length is shortened, and therefore specific capacitance of active materials is significantly enhanced [4][5][6]. For example, 3D holey-graphene/niobia composite architectures have been designed to show ultrahigh-rate energy storage performance [7]. The highly interconnected graphene network in the 3D architecture shows excellent electron transport properties, while its hierarchical porous structure enables rapid ion transport. Although the nanostructured materials have shown extraordinary promise for electrochemical energy storage, most of the existing synthesis techniques require multistep and laborious procedures [8,9]. The dual pressure of energy needs and environmental requirements in society demand the rapid screening of exceptional performance materials to shorten R&D of advanced energy storage devices. As shown in Figure 1a, R&D of electrode materials mainly includes structure & component design, materials synthesis and performance evaluation. During these processes, materials synthesis often need longer time and complex equipments, which increase the finding time of new electrode materials. The development of easy and fast nanofabrication strategy can accelerate finding rate of new electrode materials in laboratory (Figure 1b). Furthermore, with creative design idea, the material synthesis process can be replaced or fused into one structure-performance process (Figure 1c), which not only accelerate the finding rate of new electrode materials, but also decrease the cost of searching new electrode materials. Abstract: The development of advanced electrode materials for high-performance energy storage devices becomes more and more important for growing demand of portable electronics and electrical vehicles. To speed up this process, rapid screening of exceptional materials among various morphologies, structures and sizes of materials is urgently needed. Benefitting from the advance of nanotechnology, tremendous efforts have been devoted to the development of various nanofabrication strategies for advanced electrode materials. This review focuses on the analysis of novel nanofabrication strategies and progress in the field of fast screening advanced electrode materials. The basic design principles for chemical reaction, crystallization, electrochemical reaction to control the composition and nanostructure of final electrodes are reviewed. Novel fast nanofabrication strategies, such as burning, electrochemical exfoliation, and their basic principles are also summarized. More im...
