“…This is likely due to the materials’ unique multivalent nature and highly tunable structure. In addition, vanadium-containing materials are known for their high theoretical capacity (e.g., V 2 O 5 , 589 mA h g –1 ), making them an ideal cathode for transportable and renewable ESSs. , When considering vanadium containing materials, there are four main categories into which they can be placed: vanadium oxides, vanadates, oxygen-free vanadium compounds, and vanadium phosphates. , While all are renowned for their electrochemical capabilities, only vanadium oxides and vanadates are widely considered for use in ZIB systems. The rigid structure of oxygen-free vanadium compounds and vanadium phosphates can hinder the expansion of their intercalation pathways; a crucial factor when intercalating high-energy ions, such as Zn 2+ , as they are prone to electrostatic interaction with the cathode material …”

The hydration of bilayer vanadium oxides has become the focus of several recent studies toward increasing the interlayer spacing and improving their structural stability, which is favorable for the reversible (de)insertion of Zn2+ ions. However, there is limited understanding on the optimal level of H2O molecules to be incorporated within the vanadium oxide structure. Herein, we investigate the effects of the interlayer H2O content in a vanadium(IV,V) oxide-based cathode material toward the electrochemical performance of a zinc-ion battery (ZIB). A simple solvothermal synthetic route was employed to synthesize carbon-integrated hydrated vanadium oxides with varying H2O contents, CHVO (V5O12·2.7H2O) and CHVO-LW (V5O12·0.4H2O). CHVO material displays a high capacity of 396 mA h g–1 at a specific current of 250 mA g–1 and an excellent rate capability (187 W h kg–1 at a high-power density of 4.5 kW kg–1). In contrast, CHVO-LW delivers a higher capacity of 582 mA h g–1 at 200 mA g–1 in the initial cycles, however, suffers a rapid capacity decay and cell failure in subsequent cycles. Electrochemical characterizations revealed that structural pillars, such as H2O molecules, can indeed provide significant structural stability, yet too many of them can block intercalation pathways leading to lower capacity. This study shows the importance of adjusting the hydration level to sustain a balance between the high capacity and long-term stability of hydrated vanadium oxide cathode-based ZIBs.

However, the organic electrolytes used in LIBs are highly toxic and flammable, and are deemed safety hazards. The limited resources and high-cost of lithium and harsh assemble conditions of LIB cells also hinder the application of LIBs in large-scale energy storage systems. [2] P. Rüetschi proposed the '3 E' criteria including Energy, Economics, and Environment to determine whether the battery system was practical for daily use. [3] Aqueous electrolytes with low price, high safety, and high conductivity can drastically reduce the production cost and improve battery safety. [4] Aqueous zincion batteries (ZIBs) use Zinc as an environment-friendly anode which shows low redox potential (−0.78 eV vs SHE), high electronic conductivity as well as large capacity (820 mAh g −1 and 5851 mAh cm −3 ). [5,6] Therefore, ZIBs are considered as one of the most competitive and promising development directions for next-generation large-scale energy storage. As the initial work in mild aqueous electrolyte, an aqueous ZIB with MnO 2 cathode and Zn anode was reported by Kang and co-workers in 2012. [7] Since then, research interests in ZIBs area develops burgeoningly and more than 1000 research papers about electrode materials on aqueous ZIBs were published.The commonly reported cathode materials are V-based compounds, [8,9] manganese oxides, [10,11] Prussian blue analogs, [12,13] metal chalcogenides, [14,15] and organic compounds. [16,17] Among them, manganese oxides have moderate operating potential and high theoretical capacity, but suffer from manganese dissolution in aqueous electrolytes due to Jahn-Teller dissolution of Mn 3+ , which leads to structural collapse and poor cycling stability. [10,11] Prussian blue analogs often process high operating potential beyond 1.5 V and their open cage-like framework guarantees structure stability under rapid Zn 2+ transmission, leading to good rate performance and long-cycle capacity retention. However, the large framework structures also bring limited theoretical capacity and suffer from O 2 evolution due to the high operating potential. [13,18] Organic cathodes process passable theoretical capacity, high structural diversity, and flexibility, bringing potential prospects in flexible electrodes. But the high dissolubility in electrolytes and high resistance are two bumps to overcome for organic cathodes used in ZIBs. [16,17] V-based compounds have received extensive attention as cathode for ZIBs due to the rich reserves and diversity of valences of vanadium as well as their general high theoretical capacity and Aqueous zinc-ion batteries (ZIBs) have been promptly developed as a competitive and promising system for future large-scale energy storage. In recent years, vanadium (V)-based compounds, with diversity of valences and high electrochemical-activity, have been widely studied as cathodes for aqueous ZIBs because of their rich reserves and high theoretical capacity. However, the stubborn issues including low conductivity and sluggish kinetics, plague their smooth application in aqueous...

“…VOs have mixed valence (V 2+ to V 5+ ), an open structure, layered frameworks, and an easily controllable interlayer spacing, making them an excellent contender for a wide range of redox-dependent applications. 20,21 Much efforts have been made to fabricate zinc-vanadium oxide rechargeable batteries in conventional coin cell configurations. Different phases of VOs, e.g., V 2 O 5 , V 3 O 7 , V 2 O 3 , V 6 O 13 , VO 2 , V 10 O 24 , metal-doped vanadium oxides, 22,23 etc., have been explored as cathode materials.…”

Herein we demonstrate the fabrication of a highperformance rechargeable zinc ion battery based on a laser-scribed carbon (LSC)-supported electrodeposited zinc anode and vanadium oxide (V 5 O 12 •6H 2 O) cathode with a planar-interdigitated electrode architecture and a polymeric solid electrolyte. This is the first report on a full-cell Zn//V 5 O 12 •6H 2 O planar flexible battery where a practical zinc loading (∼76 times that of the cathode loading) is maintained. The electrodeposited Zn@LSC anode showed excellent stability with very low polarization over the tested 500 h (750 cycles). We demonstrate a high initial capacity of 325 mAh/g for the Zn//V 5 O 12 •6H 2 O planar battery at 2 A/g in a 3 M ZnSO 4 aqueous electrolyte. However, the capacity dropped to 70 mAh/g only after 1000 cycles. Nonetheless, the cell performance, in particular the cycle stability, was significantly improved when the aqueous electrolyte was replaced with a gelatin/ZnSO 4 / glutaraldehyde-based solid-state electrolyte. The solid-state planar battery showed a high initial capacity of 556 mAh/g at 0.1 A/g current corresponding to an energy density of 381 Wh/kg active cathode and an impressive cycle stability with only 0.0067% capacity loss per cycle over 5500 cycles at 2 A/g. The cell also demonstrated excellent flexibility with comparable specific capacity under different bending conditions. The solid-state device exhibited a high areal energy density of 72 and 14 μWh/cm 2 at the corresponding areal power density of 130 and 2511 μW/cm 2 , respectively. Overall, the rapid (complete device fabrication in ∼2 h) and scalable fabrication approach, high performance with excellent safety features, and accompanying high flexibility make the as-fabricated Zn// V 5 O 12 •6H 2 O planar flexible battery suitable for next-generation flexible electronics applications.
