Vanadium-based intercalation materials have attracted considerable attention for aqueous zinc-ion batteries (ZIBs). However, the sluggish interlaminar diffusion of zinc ions due to the strong electrostatic interaction, severely restricts their practical application. Herein, oxygen vacancy-enriched V2O5 structures (Zn0.125V2O5·0.95H2O nanoflowers, Ov-ZVO) with expanded interlamellar space and excellent structural stability are prepared for superior ZIBs. In situ electron paramagnetic resonance (EPR) and X-ray diffraction (XRD) characterization revealed that numerous oxygen vacancies are generated at a relatively low reaction temperature because of partially escaped lattice water. In situ spectroscopy and density functional theory (DFT) calculations unraveled that the existence of oxygen vacancies lowered Zn2+ diffusion barriers in Ov-ZVO and weakened the interaction between Zn and O atoms, thus contributing to excellent electrochemical performance. The Zn||Ov-ZVO battery displayed a remarkable capacity of 402 mAh g−1 at 0.1 A g−1 and impressive energy output of 193 Wh kg−1 at 2673 W kg−1. As a proof of concept, the Zn||Ov-ZVO pouch cell can reach a high capacity of 350 mAh g−1 at 0.5 A g−1, demonstrating its enormous potential for practical application. This study provides fundamental insights into formation of oxygen-vacant nanostructures and generated oxygen vacancies improving electrochemical performance, directing new pathways toward defect-functionalized advanced materials. 相似文献

Bromine-based flow batteries (Br-FBs) are considered one of the most promising energy storage systems due to their features of high energy density and low cost. However, they generally suffer from uncontrolled diffusion of corrosive bromine particularly at high temperatures. That is because the interaction between polybromide anions and the commonly used complexing agent (N–methyl–N–ethyl–pyrrolidinium bromide [MEP]) decreases with increasing temperatures, which causes serious self-discharge and capacity fade. Herein, a novel bromine complexing agent, 1–ethyl–2–methyl–pyridinium bromide (BCA), is introduced in Br-FBs to solve the above problems. It is proven that BCA can combine with polybromide anions very well even at a high temperature of 60 °C. Moreover, the BCA contributes to decreasing the electrochemical polarization of Br−/Br2 couple, which in turn improves their power density. As a result, a zinc–bromine flow battery with BCA as the complexing agent can achieve a high energy efficiency of 84% at 40 mA cm−2, even at high temperature of 60 °C and it can stably run for more than 400 cycles without obvious performance decay. This paper provides an effective complexing agent to enable a wide temperature range Br-FB. 相似文献

Conventional bulky and rigid power systems are incapable of meeting flexibility and breathability requirements for wearable applications. Despite the tremendous efforts dedicated to developing various 1D energy storage devices with sufficient flexibility, challenges remain pertaining to fabrication scalability, cost, and efficiency. Here, a scalable, low‐cost, and high‐efficiency 3D printing technology is applied to fabricate a flexible all‐fiber lithium‐ion battery (LIB). Highly viscous polymer inks containing carbon nanotubes and either lithium iron phosphate (LFP) or lithium titanium oxide (LTO) are used to print LFP fiber cathodes and LTO fiber anodes, respectively. Both fiber electrodes demonstrate good flexibility and high electrochemical performance in half‐cell configurations. All‐fiber LIB can be successfully assembled by twisting the as‐printed LFP and LTO fibers together with gel polymer as the quasi‐solid electrolyte. The all‐fiber device exhibits a high specific capacity of ≈110 mAh g?1 at a current density of 50 mA g?1 and maintains a good flexibility of the fiber electrodes, which can be potentially integrated into textile fabrics for future wearable electronic applications. 相似文献

Rechargeable aqueous zinc‐ion batteries hold great promise for potential applications in large‐scale energy storage, but the reversible insertion of bivalent Zn2+ and fast reaction kinetics remain elusive goals. Hence, a highly reversible Zn/VNx Oy battery is developed, which combines the insertion/extraction reaction and pseudo‐capacitance‐liked surface redox reaction mechanism. The energy storage is induced by a simultaneous reversible cationic (V3+ ? V2+) and anionic (N3? ? N2?) redox reaction, which are mainly responsible for the high reversibility and no structural degradation of VNxOy. As expected, a superior rate capability of 200 mA h g?1 at 30 A g?1 and high cycling stability up to 2000 cycles are achieved. This finding opens new opportunities for the design of high‐performance cathodes with fast Zn2+ reaction kinetics for advanced aqueous zinc‐ion batteries. 相似文献

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. 相似文献

Aqueous zinc-ion battery (AZIBs) is expected to be an ideal device for large-scale energy storage for its high safety and low cost. However, it is still a challenge to achieve both high energy density and high stability. Herein, in situ liquid-phase growth exfoliation is developed to obtain V5O12 nanosheets, which is then combined with Ti3C2 nanosheets to construct two-dimensional heterostructure (2D HVO@Ti3C2) with interfacial V O Ti bonds. 2D HVO@Ti3C2 exhibits a dynamic interface coupling during discharging/charging, accompanied by break/reconstruction of interfacial V O Ti bonds. The dynamic interface coupling provides a reversible electron transfer channel and endows the inert Ti3C2 with electrochemical activity in AZIBs, making it an additional electron acceptor and donor, and promoting the insertion of more Zn2+. Therefore, a capacity beyond the theoretical capacity of HVO is obtained for the HVO@Ti3C2. Additionally, the reversible 2D dynamic interface coupling can also effectively alleviate the structural damage during the cycling process. Then, the ultra-high capacity (457.1 mAh g-1 at 0.2 A g-1, over 600 mAh g-1 based on the mass of HVO) and high stability (88.9% capacity retention after 1000 cycles at 5 A g-1) are achieved. This interface coupling mechanism provides an exciting strategy for the high energy density and high stability of AZIBs. 相似文献

The cycle life of aqueous zinc-ion batteries (ZIBs) is limited by the notable challenges of cathode dissolution, water reactivity, and zinc dendrites. Here, it is demonstrated that by tuning the electrolyte solvation structure, the issues for both the electrodes and the electrolyte can be addressed simultaneously. Specifically, a fire-retardant triethyl phosphate (TEP) is demonstrated as a cosolvent with strong solvating ability in a nonaqueous/aqueous hybrid electrolyte. The TEP features a higher donor number (26 kcal mol−1) than H2O (18 kcal mol−1), preferring to form a TEP occupied inner solvation sheath around Zn2+ and strong hydrogen bonding with H2O. The TEP coordinated electrolyte structure can inhibit the reactivity of H2O with V2O5 and leads to a robust polymeric-inorganic interphase (poly-ZnP2O6 and ZnF2) on zinc anode effectively preventing the dendrite growth and parasitic water reaction. With such an optimized electrolyte, the Zn/Cu cells perform high average Coulombic efficiency of 99.5%, and the full cell with a low capacity ratio of Zn:V2O5 (2:1) and lean electrolyte (11.5 g Ah−1) delivers a reversible capacity of 250 mAh g−1 for over 1000 cycles at 5 A g−1. This study highlights the promise of a successful electrolyte regulation strategy for the development of high-performance and practical ZIBs. 相似文献

Aqueous zinc-based energy storage systems (Zn-ESSs) with intrinsic safety and good electrochemical performance are promising power suppliers for flexible electronics, whereas unstable zinc anodes especially in flexible Zn-ESSs pose a challenge. Herein, a self-assembled robust interfacial layer to achieve stable zinc anodes in non-flexible and flexible Zn-ESSs is reported. Specifically, zinc anodes and their slowly-released Zn2+ simultaneously interact with tannic acid molecules in ethanol–water solutions, triggering the self-assembly of a tannic acid/Zn2+ complex interfacial layer (CIL) that firmly anchors on the zinc anodes. The CIL containing abundant carboxyl and phenolic hydroxyl functional groups provides rich zincophilic sites to homogenize Zn2+ flux and accelerate Zn2+ desolvation-deposition, and traps H+/H2O species to prevent them from corroding zinc anodes, thereby stabilizing the zinc deposition interface. Consequently, the CIL@Zn anodes present superior stability with an operation lifetime exceeding 700 h even at 5 mA cm−2 (28 times longer than that of bare zinc anodes) and ultrahigh cumulative plated capacity of ≈1.8 Ah cm−2. The firm anchoring of the CIL enables the CIL@Zn anodes to endure diverse deformations, thus realizing highly flexible CIL@Zn anode-based Zn-ESSs. This work provides thinking in designing stable and flexible zinc anodes, promoting the development of flexible zinc-based energy storage. 相似文献

What has been a crucial demand is that designing mighty cathode materials for aqueous zinc−ion batteries (AZIBs), which are vigorous alternative devices for large−scale energy storage by means of their high safety and low cost. Herein, a facile strategy is designed that combines oxygen defect engineering with polymer coating in a synergistic action. As an example, the oxygen−deficient hydrate vanadium dioxide with polypyrrole coating (Od−HVO@PPy) is synthesized via a one-step hydrothermal method in which introducing oxygen vacancy in HVO is simultaneously realized during the in situ polymerization. Such a desirable material adjusts the surface adsorption and internal diffusion of Zn2+ demonstrated by electrochemical characterization and theoretical calculation results. Moreover, it also utilizes conductive polymer coating to improve electrical conductivity and suppress cathode dissolution. Therefore, the Od−HVO@PPy electrode delivers a preferable reversible capacity (337 mAh g−1 at 0.2 A g−1) with an impressive energy density of 228 Wh kg−1 and stable long cycle life. This enlightened design opens up a new modus operandi toward superior cathode materials for advanced AZIBs. 相似文献

Wearable electronic devices that can be directly worn on the human body or combined with daily textiles have experienced a booming development with the rapid development of mobile electronics. These wearable electronic devices strongly demand indispensable, high performance power systems with small size, high flexibility, and adaptability to comfort frequent deformations during usage. Fabricating high‐performance energy storage systems in a 1D shape like fiber is recognized as a promising strategy to address the above issues. These fiber‐shaped power systems with diameters from tens to hundreds of micrometers can adapt to various deformations for stable operation in close contact with the human body. It is also possible to further weave such 1D energy storage devices into breathable textiles with matching electrochemical performances for the wearable electronics. Here, the key advancements related to fiber‐shaped energy storage devices are reviewed, including the synthesis of materials, the design of structures, and the optimization of properties for the most explored energy storage devices, i.e., supercapacitors, aprotic lithium‐based batteries, as well as novel aqueous battery systems. The remaining challenges are finally discussed to highlight the future direction of the development of fiber‐shaped energy storage devices. 相似文献

Anode-free zinc batteries (AFZBs) are proposed as promising energy storage systems due to their high energy density, inherent safety, low cost, and simplified fabrication process. However, rapid capacity fading caused by the side reactions between the in situ formed zinc metal anode and electrolyte hinders their practical applications. To address these issues, aqueous AFZBs enabled by electrolyte engineering to form a stable interphase are designed. By introducing a multifunctional zinc fluoride (ZnF2) additive into the electrolyte, a stable F-rich interfacial layer is formed. This interfacial layer can not only regulate the growth orientation of zinc crystals, but also serve as an inert protection layer against side reactions such as H2 generation. Based on these synergy effects, zinc deposition/dissolution with high reversibility (Coulombic efficiency > 99.87%) and stable cycling performance up to 600 h of are achieved in the electrolyte optimized by ZnF2. With this electrolyte, the cycling life of AFZBs is significantly improved. The work may initiate the research of AFZBs and be useful for the design of high energy, high safety, and low-cost power sources. 相似文献

A novel lyotropic liquid‐crystal (LC) based assembly strategy is developed for the first time, to fabricate composite films of vanadium pentoxide (V2O5) nanobelts and graphene oxide (GO) sheets, with highly oriented layered structures. It is found that similar lamellar LC phases can be simply established by V2O5 nanobelts alone or by a mixture of V2O5 nanobelts and GO nanosheets in their aqueous dispersions. More importantly, the LC phases can be retained with any proportion of V2O5 nanobelts and GO, which allows facile optimization of the ratio of each component in the resulting films. Named VrGO, composite films manifest high electrical conductivity, good mechanical stability, and excellent flexibility, which allow them to be utilized as high performance electrodes in flexible energy storage devices. As demonstrated in this work, the VrGO films containing 67 wt% V2O5 exhibit excellent capacitance of 166 F g?1 at 10 A g?1; superior to those of the previously reported composites of V2O5 and nanocarbon. Moreover, the VrGO film in flexible lithium ion batteries delivers a high capacity of 215 mAh g?1 at 0.1 A g?1; comparable to the best V2O5 based cathode materials. 相似文献

Quasi-solid aqueous zinc ion batteries (AZIBs) based on flexible hydrogel electrolytes are promising substitutions of lithium-ion batteries owing to their intrinsic safety, low cost, eco-friendliness and wearability. However, it remains a challenge to lower the freezing point without sacrificing the fundamental advantages of hydrogel electrolytes such as conductivity and mechanical properties. Herein, an all-around hydrogel electrolyte is constructed through a convenient energy dissipation strategy via the rapid and reversible intramolecular/intermolecular ligand exchanges between Zn2+ and alterdentate ligands. The as-obtained hydrogel exhibits excellent mechanical properties, fatigue resistance, high Zn-ion conductivity (38.2 mS cm−1), good adhesion (19.1 kPa), and ultra-low freezing point (−97 °C). Due to the alterdentate ligands help to improve the zinc ion solvation structure and guide uniform Zn deposition, the Zn||Zn symmetric cells show stable plating/stripping behavior and long-term cycle stability. The Zn||V2O5 full cells exhibit large capacity of 230.6 mAh g−1 and high capacity retention of 75.2% after 1000 cycles. Furthermore, flexible AZIBs operate stably even under extreme conditions including low temperature (−40 °C) and large bending angle (180°). The mechanically damage-resistant hydrogel can also be utilized in flexible strain sensors. This work offers a facile strategy for developing mechanically deformation-resistant, dendrite-free, and environmentally adaptable AZIBs. 相似文献

Rechargeable hydrogen gas batteries are highly desirable for large-scale energy storage because of their long life cycle, high round trip efficiency, fast reaction kinetics, and hydrogen gas profusion. Coupling advanced cathode chemistries with hydrogen gas anode is an emerging and exciting area of research. Here, a novel high-performance aqueous iodine-hydrogen gas (I2-H2) battery using iodine as cathode and hydrogen gas as the electrocatalytic anode in environmentally benign aqueous electrolytes is reported. The working chemistry of the battery involves I2/I− solid-liquid reactions occurring over the cathode along with H2/H2O gas-liquid reactions at the anode, achieving a high rate performance of 100 C and long-lasting stability of over 60 000 cycles. Additionally, the static aqueous I2-H2 battery displays a volumetric capacity of 15.5 Ah L−1 along with good self-healing capability towards cell overcharge. The current battery design exhibits robust electrochemical performance irrespective of acidic, neutral, and alkaline electrolyte systems. This study paves the way towards the industrialization of economically effective, high-power density, and long-term I2-H2 batteries for large-scale energy storage applications. 相似文献

An extremely stable, energy-dense (53.6 Ah L−1, 2 m transferrable electrons), low crossover (permeability of <1 × 10−13 cm2 s−1 using Nafion 212 (Nafion is a trademark polymer from DuPont)), and potentially inexpensive anthraquinone with 2-2-propionate ether anthraquinone structure (abbreviated 2-2PEAQ) is synthesized and extensively evaluated under practically relevant conditions for use in the negolyte of an aqueous redox flow battery. 2-2PEAQ shows a high stability with a fade rate of 0.03–0.05% per day at different applied current densities, cut-off voltage windows, and concentrations (0.1 and 1.0 m ) in both a full cell paired with a ferro/ferricyanide posolyte as well as a symmetric cell. 2-2PEAQ is further shown to have extreme long-term stability, losing only ≈0.01% per day when an electrochemical rejuvenation strategy is employed. From post-mortem analysis (nuclear magnetic resonance (NMR), liquid chromatography–mass spectrometry (LC-MS), and cyclic voltammetry (CV)) two degradation mechanisms are deduced: side chain loss and anthrone formation. 2-2PEAQ with the ether linkages attached on carbons non-adjacent to the central ring is found to have three times lower fade rate compared to its isomer with ether linkages on the carbon adjacent to the central quinone ring. The present study introduces a viable negolyte candidate for grid-scale aqueous organic redox flow batteries. 相似文献

Aqueous Zn metal batteries are regarded as a promising pathway for large-scale energy storage systems due to their green, low-cost, and intrinsically safe characteristics. However, they have long been suffered from narrow voltage windows and severe parasitic reactions (e.g., hydrogen evolution, corrosion, etc.), which hinder their further development. The above challenges are essentially related to the existence of hydrated ions (i.e., Zn(H2O)x2+ and SO42−·(H2O)x), which are highly reactive species. Herein, a counterintuitive ultralow-salt-concentration electrolyte strategy to solve the aforementioned problems by decreasing Zn salt concentration to reduce active hydrated ions is presented, so as to minimize water-induced side reactions and thus anomalously enlarge the electrolyte splitting voltage window. Additionally, the gap between the charge and discharge medium voltages of full cells is also narrowed due to the reduced polarization in the ultralow-salt-concentration electrolyte. By adopting this strategy, the Zn-Fe4[Fe(CN)6]3 full cell stably works at a high-voltage of 1.40–2.30 V with a high cathode loading of ≈7 mg cm−2 and the Zn-polyaniline full cell can stably work at 0.50–1.50 V with a high cathode loading of ≈11 mg cm−2. 相似文献
