Aqueous zinc ion batteries (AZIBs) have been widely investigated due to their characteristics of convenient operation and intrinsic safety. However, there are several issues to be addressed in AZIBs, such as slow diffusion kinetics of Zn2+, cathode material dissolution and the dendrite formation of zinc anodes. Thus, it is challenging to prepare a high-performance cathode material. In this work, we prepare NH4V4O10 flower-like structures by a facile hydrothermal route. The introduction of chitosan significantly enlarges the layer spacing of the (001) crystal plane. The assembled Zn//NVO-0.15C batteries deliver a specific capacity of 520.54 mA h g−1 at a current density of 0.2 A g−1. Furthermore, they maintain 91% of the retention rate at 5.0 A g−1 after 1000 times cycling. It demonstrates the excellent zinc ion storage behavior of ammonium vanadate electrode materials for AZIBs.

Herein, oxygen-deficient NH 4 V 4 O 10 micro-flowers with loaded Ag quantum dots and pre-intercalated Ag + (NVO-Ag) for aqueous zinc ion battery (AZIB) cathode materials were successfully synthesized by a one-step hydrothermal method. The reversible redox reaction between Ag + and Ag quantum dots, and the abundant Zn 2+ storage sites from oxygen vacancies provided capacity contributions for NVO-Ag. Meanwhile, the loaded Ag quantum dots, pre-intercalated Ag + and introduced oxygen vacancies synergistically optimized the electronic structure and distribution of NVO-Ag, promoting the transport of electrons in NVO-Ag. The pre-intercalated Ag + could also replace the NH 4 + in the interlayer of NH 4 V 4 O 10 , weakening the repulsion between the interlayer NH 4 + and Zn 2+ , which achieved rapid Zn 2+ diffusion kinetics. Moreover, the abundant oxygen vacancies in NVO-Ag could alleviate the strong electrostatic interaction between Zn 2+ and V-O framework, boosting the transmission of Zn 2+ in NVO-Ag. Finally, the structural stability of NH 4 V 4 O 10 micro-flowers was improved due to the high bonding strength between Ag + and V-O layers. Benefiting from the above effects, NVO-Ag-100 achieved excellent capacity performance (387.2 mAh g −1 at 0.5 A g −1 ), rate performance (178.9 mAh g −1 at 12 A g −1 ) and cycle stability (91.7 % capacity retention after 1700 cycles at 8 A g −1 ). This work provided effective ideas to achieve high-performance AZIB cathode materials.

Capacitive deionization (CDI) has developed rapidly due to its advantages of low energy consumption and eco-friendliness. In recent years, many researchers have devoted their efforts to fabricating new electrode materials in order to achieve superior desalination efficiency and excellent long-term recycling stability. Herein, a new CDI cathode material — an NH4V4O10/rGO (NHVO/rGO) composite — was synthesized using a simple hydrothermal process. The as-prepared ammonium vanadium bronze NH4V4O10 (NHVO) displayed a large 2D layer spacing, of about 1.0 nm, and was hence tested as a potential Na+-intercalating material. The graphene present in the composite played a significant role in improving the electrical conductivity of NHVO, greatly promoting its desalting efficiency. During desalination tests, an NHVO/rGO-based CDI system delivered a NaCl removal capacity of 20.1 mg g−1 at an applied voltage of 1.2 V in a 500 mg L−1 NaCl solution; that is, the NHVO/rGO composite displayed a remarkable salt removal performance. Due to the excellent desalination performance of this system, the NH4V4O10/rGO composite is expected to become an appealing candidate for enhancing the performance of CDI electrodes.

Ammonium vanadate has increasingly been the focus of attention in the field of aqueous zinc ion battery due to its high theoretical specific capacity. However, they suffer from slow kinetics and loss of capacity due to irreversible deamidation. Herein, we fabricated a series of Na + -intercalating NH 4 V 4 O 10 (SNVO) with lamellar structure via a simple one-step hydrothermal method, in which SNVO30 exhibited high capacity and satisfactory rate performance in the storage process for Zn 2+ . Sodium alginate had a role in the modulation of microstructures during the synthesis, which improved the contact area between the cathode and the electrolyte. It was found that Na + increased the interlayer spacing, and served as a “pillar” between the V O layers to reinforce the SNVO during the cycling process, thereby enhancing its stability and accelerating reaction kinetics. The generation of additional oxygen vacancies facilitated an alteration in the electronic structure and enhanced the Zn 2+ diffusion capacity. Specifically, the SNVO30 exhibited high initial specific capacity of 447.2 mAh g −1 at 2.0 A g −1 . And a specific capacity of 228.3 mAh g −1 was maintained after 1500 cycles at 10 A g −1 . This work provides a reference for the development of high-performance aqueous zinc ion battery cathode materials.

Ammonium vanadate (NH 4 V 4 O 10 ) is supposed to be the most potential cathode candidates for aqueous zinc ion batteries (AZIBs) due to its stable layered structure and high theoretical capacity. However, the strong electrostatic interaction between Zn 2+ and NH 4 V 4 O 10 lattice impede its further application. Herein, an efficient hydrothermal method was used to synthesize poly(3, 4-ethylenedioxythiophene) pre-intercalated NH 4 V 4 O 10 (NVO-PEDOT), which shows promising Zn 2+ storage properties as a cathode material for AZIBs. The NVO-PEDOT presents flower-like morphology composed of nanoribbons, which can shorten Zn 2+ diffusion path. Moreover, the pre-intercalated PEDOT introduces oxygen vacancies and low valence vanadium, which not only weaken electrostatic interaction between Zn 2+ and NH 4 V 4 O 10 , but also enhance electronic conductivity, promoting the reversibility of NH 4 V 4 O 10 toward the de−/intercalation of Zn 2+ . Accordingly, NVO-PEDOT cathode provides high reversible capacity (381 mA h g −1 at 0.1 A g −1 after 87 cycles), excellent rate capability (130 mA h g −1 at 20 A g −1 ) and long-life cycling (105 mA h g −1 after 1500 cycles at 10 A g −1 ), confirming the effective synthesis strategy of NH 4 V 4 O 10 cathode for high performance AZIBs.

Self-powered wearable electronic devices have developed rapidly in the wearable field by integrating multi-functional sensing and energy storage functions at the same time. However, the integration of the system and the uniformity of materials still restrict the wide application of devices. In this study, a multifunctional PANI@NH 4 V 4 O 10 @CC composite material with a hierarchical microstructure was successfully synthesized, simultaneously fulfilling the demands for both sensing and energy storage. For energy storage application, the assembled asymmetric supercapacitor achieves an areal capacitance of 617 mF cm −2 and a power density of 0.514 W cm −2 . Regarding sensing, due to hierarchical microstructure and, the fabricated sensor exhibits ultra-high sensitivity (6.1×10 4 kPa −1 ) over a wide pressure range (0–200,000 Pa), ultra-fast response/recovery kinetics (90 ms), and minimal performance degradation after 12,000 pressure cycles. Additionally, the composite material demonstrates photoelectric conversion capabilities, displaying a linear response with illumination intensity ranging from 10 to 100 mW cm −2 . By the synergistic integration of pressure sensing and supercapacitor functionalities, high-precision gesture recognition systems (recognition accuracy of 95.45 %) and high-resolution spatial pressure mapping applications are enabled. This approach provides a multifunctional material platform for next-generation self-powered wearable electronics and facilitates progress in the advancement of wearable smart devices.

Zn-doped V 2 O 5 /NH 4 V 4 O 10 heterojunction in-situ constructed on carbon cloth. • Electronic mismatch drives interfacial charge rearrangement and coupling. • Heterointerface boosts Zn 2+ kinetics and suppresses V dissolution to prevent degradation. • Heterostructure cathode delivers high capacity and ultra-stable cycle life. Layered vanadium-based heterojunctions and cation pre-intercalation serve as effective strategies to address sluggish ion diffusion and inferior structural stability of aqueous zinc-ion batteries. Herein, hierarchical Zn-doped V 2 O 5 /NH 4 V 4 O 10 heterojunction is in-situ grown on carbon cloth via two-step hydrothermal treatment. The fabricated heterojunction accelerates Zn 2+ migration and eliminates discharge kinetic limitations of pristine cathode materials. It also restrains Jahn-Teller distortion to mitigate lattice degradation and improve structural reversibility. Benefiting from structural and interfacial advantages, the obtained cathode delivers a high specific capacity of 523.8 mA h g −1 , outstanding rate performance and 72.4% capacity retention over 3000 cycles at 3 A g −1 . It maintains 171.4 mA h g −1 at 5 A g −1 and exhibits 96.37% capacity recovery after current adjustment. This work offers a promising interfacial engineering route for advanced aqueous zinc-ion battery cathodes and expands the application prospect of vanadium-based layered heterostructures.

Ammonium vanadate (NH 4 V 4 O 10 : NVO) as cathode for rechargeable aqueous zinc-ion batteries (AZIBs) have drawn extensive concern due to its high specific capacity and long cycle life. The controllable synthesis of high-performance NH 4 V 4 O 10 is greatly desirable for the development of AZIBs but still remains a significant challenge. In this work, sulfuric acid, hydrochloric acid, and nitric acid were used as pH regulators to prepare NVO via a simple one-step hydrothermal route. The resulting NVO product (NVO-1) based on sulfuric acid pH regulator has the optimal overall performance for its favorable structure stability originated from the high crystallinity and wonderful 3D cross-linked nanowire morphology, contributing to fast electron transfer in the (de)intercalation process of Zn 2+ . Consequently, NVO-1 electrode exhibits excellent rate capability and cyclic stability, delivering high reversible capacities of 418.9 and 257.1 mAh g −1 at current densities of 0.1 and 2 A g −1 , respectively, and demonstrating a discharge capacity of 105.7 mAh g −1 as well as superior long-term durability with an ultra-high capacity retention of 119.7 % at a large current density of 5 A g −1 after 2000 cycles. Investigation on the electrochemical kinetics reveals that surface capacitive behavior plays a significant role in the highly reversible Zn 2+ storage in NVO electrode.

Rampant side reactions such as hydrogen evolution reaction (HER), corrosion and uncontrollable dendrite growth at anodes greatly impede the application of AZIBs . Herein, caprolactam (CPL) is employed as a crucial electrolyte medium to achieve the aim of highly reversible zinc anodes . CPL molecules exhibit a lower adsorption energy (−1.94 eV) than H 2 O and preferential binding with Zn anodes, resulting in a H 2 O-poor anode/electrolyte interface and an enhanced steric effect at the anode surface. This effect effectively hinders the contact between zinc metal and water molecules, consequently facilitating the uniform and controlled deposition of Zn 2+ . Furthermore, the combination between CPL and Zn 2+ contributes to the optimization of solvation structures. Consequently, Zn/Zn batteries with CPL additives realized more than 2100 h stable cycling life under 1 mA cm −2 and 1 mAh cm −2 . Moreover, Zn/Cu batteries with CPL additives achieved a reversible plating/stripping process for over 3000 cycles with high average CE of 99.4%. Besides, the assembled Zn/NH 4 V 4 O 10 full batteries using electrolyte of ZnSO 4 /CPL also exhibited excellent cyclic performance. The batteries yielded 77.1 mAh g −1 under the current density of 5 A g −1 after 1000 cycles. CPL demonstrates significant potential as a cost-effective and multifunctional electrolyte additive for achieving stable and reliable AZIBs.

Aqueous zinc-ion batteries (AZIBs) are promising for grid-scale energy storage but suffer from Zn anode instability caused by dendrite growth, hydrogen evolution, and corrosion. In this work, L-carnosine (L-C), a natural dipeptide, is introduced as an electrolyte additive to address these challenges, due to its dual ion-chelating and Zn-adsorbing capabilities. It is demonstrated that L-C can regulate Zn 2+ solvation structures by displacing water molecules via strong coordination bonds. Simultaneously, L-C can preferentially adsorb on Zn surfaces, guiding uniform Zn deposition along the (101) plane and forming a dynamic protective layer that dynamically repairs interfacial defects. This self-healing capability enables short-circuited Zn anodes to recover stable cycling for over 2000 h, while pre-scratched surfaces are fully restored during cycling. These synergistic mechanisms enable Zn||Zn symmetric cells to achieve exceptional cycling stability (>5400 h at 1 mA cm −2 , 1 mAh cm −2 ) and high-rate durability (>1100 h at 5 mA cm −2 , 5 mAh cm −2 ). Full cells, paired with NH 4 V 4 O 10 (NHVO) cathodes, retain 82.26% capacity after 2000 cycles at 5 A g −1 , highlighting practical viability. The bioinspired solvation-interfacial dual-regulation strategy provides a universal approach for designing eco-friendly, high-performance AZIBs.
