Exploration of high‐performance cathode materials for rechargeable aqueous Zn ion batteries (ZIBs) is highly desirable. The potential of molybdenum trioxide (MoO 3 ) in other electrochemical energy storage devices has been revealed but held understudied in ZIBs. Herein, a demonstration of orthorhombic MoO 3 as an ultrahigh‐capacity cathode material in ZIBs is presented. The energy storage mechanism of the MoO 3 nanowires based on Zn 2+ intercalation/deintercalation and its electrochemical instability mechanism are particularly investigated and elucidated. The severe capacity decay of the MoO 3 nanowires during charging/discharging cycles arises from the dissolution and the structural collapse of MoO 3 in aqueous electrolyte. To this end, an effective strategy to stabilize MoO 3 nanowires by using a quasi‐solid‐state poly(vinyl alcohol)(PVA)/ZnCl 2 gel electrolyte to replace the aqueous electrolyte is developed. The capacity retention of the assembled ZIBs after 400 charge/discharge cycles at 6.0 A g −1 is significantly boosted, from 27.1% (in aqueous electrolyte) to 70.4% (in gel electrolyte). More remarkably, the stabilized quasi‐solid‐state ZIBs achieve an attracting areal capacity of 2.65 mAh cm −2 and a gravimetric capacity of 241.3 mAh g −1 at 0.4 A g −1 , outperforming most of recently reported ZIBs.

safety, and low cost. [1][2][3][4][5] However, the strong electrostatic interaction with host materials originating from divalent chemistry leads to low output voltage, poor reversibility, and especially sluggish kinetics. Various cathode materials have been developed to navigate these challenges. Currently, the most studied cathode active materials are manganesebased [6][7][8][9] and vanadium-based [10][11][12][13] composites. Nonetheless, relative low operating voltage and poor rate performance remains as issues. To reach the operating voltage of electronic devices, multiple batteries must be connected in series. This practice increases the volume of battery and causes energy loss. Furthermore, poor rate capability limits application of Zn-ion batteries in high-power appliances.The Prussian blue analogues (PBAs) possessing a 3D open framework with large interstitial sites, [4][5][6][7][8][9][10][11][12][13][14][15][16] are considered as a promising host material for reversible Zn-ion intercalation/deintercalation with fast charge/discharge properties and high operational voltage, which is ascribed to its ideal crystal structure and desirable electrochemical properties. [17] Recently, hexacyanometallates with a typical formula of A x M′[M″(CN) 6 ] y ⋅nH 2 O (simply denoted as M′/M″ PBA) are investigated as cathode active materials for aqueous batteries including Li-, Na-, Mg-, Ca-, and Zn-ion batteries, where the A Herein, a two-species redox reaction of Co(II)/Co(III) and Fe(II)/Fe(III) incorporated in cobalt hexacyanoferrate (CoFe(CN) 6 ) is proposed as a breakthrough to achieve jointly high-capacity and high-voltage aqueous Zn-ion battery. The Zn/CoFe(CN) 6 battery provides a highly operational voltage plateau of 1.75 V (vs metallic Zn) and a high capacity of 173.4 mAh g −1 at current density of 0.3 A g −1 , taking advantage of the two-species redox reaction of Co(II)/Co(III) and Fe(II)/Fe(III) couples.Even under extremely fast charge/discharge rate of 6 A g −1 , the battery delivers a sufficiently high discharge capacity of 109.5 mAh g −1 with its 3D opened structure framework. This is the highest capacity delivered among all the batteries using Prussian blue analogs (PBAs) cathode up to now. Furthermore, Zn/CoFe(CN) 6 battery achieves an excellent cycling performance of 2200 cycles without any capacity decay at coulombic efficiency of nearly 100%. One further step, a sol-gel transition strategy for hydrogel electrolyte is developed to construct high-performance flexible cable-type battery. With the strategy, the active materials can adequately contact with electrolyte, resulting in improved electrochemical performance (≈18.73% capacity increase) and mechanical robustness of the solid-state device. It is believed that this study optimizes electrodes by incorporating multi redox reaction species for high-voltage and high-capacity batteries.The ORCID identification number(s) for the author(s) of this article can be found under https://doi.

the demands for energy storage and conversion systems of high energy and power density increase rapidly. To meet the everincreasing demands, transition metal compounds have been widely studied as catalysts for chemical and energy transformation processes (e.g., oxygen reduction and evolution reaction) [1][2][3][4] and as electrode materials for rechargeable batteries [5][6][7] and supercapacitors. [8][9][10][11][12][13] For example, nickel hydroxides (Ni(OH) 2 ) have been successfully used in rechargeable alkaline batteries (due to their low-cost and high capacity) [5,14] and in hybrid supercapacitors (due to high rate capability). [15] Hybrid supercapacitors, composed of a capacitive electrode and a battery-type Faradaic electrode, have demonstrated significantly higher energy density than conventional carbon-based electrical double-layer capacitors (EDLCs), due largely to the higher capacity of the battery-type electrode and the broader voltage window of the electrode pair. [16][17][18][19][20] Moreover, hybrid supercapacitors can achieve much higher power density than rechargeable batteries. Typically, one electrode of a hybrid supercapacitor is a carbon-based material whereas the other electrode (i.e., battery-type electrode) is a lithium electroactive material (such as Sn [16] and Li 4 Ti 5 O 12 [21] ) or an anionic redox active transition metal-based oxide/hydroxide. [15,22] As a promising battery-type electrode for hybrid supercapacitor in alkaline electrolyte, Ni(OH) 2 usually exhibits a pair of distinctly separated Faradaic redox peaks due to its phase transition. [23] This material was widely reported as a "pseudocapacitive" material for supercapacitors in the past decade, [24][25][26][27][28][29][30] but has recently been regarded as a battery-type material because of its batterytype behavior in alkaline media. [31][32][33] However, Ni(OH) 2 electrodes usually suffer from an irreversible phase transition, [34,35] large volume variation, [14] and low electronic conductivity, [36] resulting in poor durability and limited rate capability.Numerous efforts have been devoted to addressing the above issues. In order to enhance the electronic conductivity, an electronically conductive second phase has been introduced [15,24,37] or Ni(OH) 2 has been grown on a conductive substrate. [28,38,39] As a highly conductive two-demonstrational material with high surface area, graphene is an ideal substrate to improve the electronic conductivity of Ni(OH) 2 . [15,24,40] To further improve Compact, light, and powerful energy storage devices are urgently needed for many emerging applications; however, the development of advanced power sources relies heavily on advances in materials innovation. Here, the findings in rational design, one-pot synthesis, and characterization of a series of Ni hydroxide-based electrode materials in alkaline media for fast energy storage are reported. Under the guidance of density functional theory calculations and experimental investigations, a composite electrode composed of Co-/Mn-substituted...
