Despite the recent resurgence of rechargeable aqueous zinc batteries (RAZBs), challenges persist for Zn metal anodes, including dendrite growth and corrosion in mild aqueous electrolytes during cycling. Developing a simple and effective solution is crucial. This study introduces a one-step strategy to create a protective layer at room temperature comprising the superconductor Nb3Sn and embedded Zn foil. The Nb3Sn–Zn composite, with a high Zn2+ transfer number and uniform nucleation sites, exhibits excellent zinc affinity and synergistic effects. This composite effectively inhibits dendrite growth by controlling Zn nucleation and prevents Zn corrosion and hydrogen evolution by shielding the Zn metal surface from electrolyte attack. The Nb3Sn–Zn composite shows remarkable electrochemical properties, including a low voltage hysteresis, high Coulombic efficiency, and prolonged cycling stability. Furthermore, a full cell utilizing the Nb3Sn–Zn anode and MnO2 cathode demonstrates superior rate capability and cycle life stability. The present research introduces an innovative methodology for the design of dendrite-free Zn anodes suitable for practical applications.

When a conventional aqueous ZnSO4 solution is used as the electrolyte, rechargeable aqueous Zn/MnO2 batteries suffer from inferior electrochemical performance because of the corrosion, dendrites, and passivation on zinc anodes. Herein, a novel gel electrolyte was fabricated by adding lignin/fumed silica composites to the reference aqueous electrolyte (RAE) (2 M ZnSO4 + 0.2 M MnSO4) for the purpose of mitigating the aforementioned issues of zinc anodes. Results of linear polarization and chronoamperometry showed that the as-prepared gel electrolyte reduced deterioration on zinc (up to 38.9%) and supported planar zinc deposits. Batteries using this gel electrolyte presented a higher open-circuit voltage after 24 h of monitoring and superior rate performance compared to batteries using the RAE. Most importantly, the discharge capacity of the batteries using this gel electrolyte after 3000 cycles at 1.5 A g–1 was still up to 106.2 mA h g–1, which was much higher than that (39.6 mA h g–1) of the batteries using the RAE. Observation through X-ray diffraction and scanning electron microscopy characterizations of the post-run zinc anodes revealed that this gel electrolyte could strongly inhibit the formation of zinc dendrites and reduce the production of byproducts (3Zn(OH)2·ZnSO4·xH2O) during the operation of the battery. This study is highly significant to the development of advanced aqueous batteries with high safety.

In this paper, LiTi 2-x Sn x (PO 4 ) 3 /C (x = 0, 0.2, 0.3, 0.4) composites were synthesized by sol-gel approach, and were investigated as anodes for aqueous lithium ion battery . Sn doping with proper content has no obvious influence on phase and morphology of the composite, while excessive dosage of Sn can affect its crystal structure. Sn doping can enhance the electrochemical properties of LiTi 2 (PO 4 ) 3 /C (LC). Among LiTi 2-x Sn x (PO 4 ) 3 /C composites, LiTi 1.7 Sn 0.3 (PO 4 ) 3 /C (LC-Sn-0.3) demonstrates the best electrochemical properties. Most importantly, the rate performance of LC can be improved dramatically by Sn doping on Ti sites. LC-Sn-0.3 delivers a discharge capacity of 118.9, 115.3, and 104.2 mAh g −1 at 0.2, 6, and 20 C (1 C = 150 mA g −1 ), respectively, with significant increase of 15.2, 27.4, and 41.9 mAh g −1 compare with LC. In addition, LC-Sn-0.3 exhibits superior cycling performance. The capacity retention for LC-Sn-0.3 can keep 76.8% after 1000 cycles at relatively high rate of 10 C, while only 51.7% of initial discharge capacity is retained for LC. Our study reveals that Sn doping on Ti sites is an efficient and facile method to improve the performance of LiTi 2 (PO 4 ) 3 /C composite for aqueous lithium ion battery.

Graphical Self-help : An omni-healable aqueous lithium-ion battery, fabricated by integrating all of the electroactive components into polymer networks cross-linked through dynamic borate ester bonding, can self-repair its electrodes and electrolyte simultaneously after mechanical breakage. It can also be tailored into complicated patterns without significant deterioration in lithium-storage properties. Reliability and safety are critical issues for portable power sources aiming for next-generation electronics. However, most lithium-ion batteries (LIBs) will fail to work or will cause safety problems after physical damage or violent deformation. Here, an omni-healable aqueous LIB, which can self-repair its electrodes and electrolyte simultaneously after mechanical breakage, is fabricated by integrating all of the electroactive components into polymer networks cross-linked by dynamic borate ester bonding. Once suffering from repeated cutoffs, the battery quickly recovers its configuration integrity as well as mechanical and electrochemical properties autonomously without external stimuli. Furthermore, the battery can also be tailored into complicated patterns while maintaining its lithium-storage properties. The present investigation offers a strategy to design a smart and sustainable energy-storage device that has potential applications in wearable/flexible electronics, flexible robot or intelligent apparel, and so on.

Recently, metal chalcogenides (MCS) with high conductivity, natural abundance and stable structure are kind of the potential cathode materials of aqueous zinc-ion batteries (ZIBs). However, compared with manganese based and vanadium based cathode materials, there are few studies and reports on MCS in the field of ZIBs. Here, for the first time, 2D layered Bi 2 Te 3 nanosheets were used as cathode to construct a novel aqueous Bi 2 Te 3 /zinc battery. A series of experiments and calculations in this work have verified that Bi 2 Te 3 nanosheets are excellent cathode material for ZIBs. Thanks to robust structure, good electronic conductivity and low zinc ion diffusion energy barrier of Bi 2 Te 3 nanosheets, the aqueous Bi 2 Te 3 /zinc battery exhibits a large reversible capacity of 413.2 mAh/g (0.4 A/g) and long lifespan of 1500 cycles (77% retention at 2 A/g) in 2 M ZnSO 4 electrolyte. Besides, the quasi-solid-state Bi 2 Te 3 /zinc battery shows excellent rate performance and high thermal stability (works well in a high temperature environment of 70 ℃). This work provides enlightenment for the development of advanced cathode materials for new generation of ZIBs with high performance, safety and stability.

Vanadium oxide with abundant interchangeable oxidation states and a variety of different crystal structures is considered to be the most promising Zn-ion host material for high-performance aqueous zinc-ion batteries (AZIBs). Nevertheless, certain constraints, including poor reversibility, low intrinsic conductivity, sluggish electrochemical kinetics, low density of exposed active sites, and low actual capacity of the material, limit their performance in AZIBs. In this work, we in situ grew 3D amorphous mixed-valence VOx microspheres on alkali-treated carbon cloth (VOx MSs@ACC) as cathodes for AZIBs. In comparison with a VOx MSs powder-constructed cathode, VOx MSs@ACC cathodes exhibit higher specific capacity (1.79 mA h cm−2 at 2.7 A m−2) and longer cycling performance over 2500 cycles mainly due to their faster ion transport rates, abundant ion storage sites and more effective easing of volume expansion. This work thus sheds light on the design of free-standing vanadium-based cathodes for AZIBs.

The development of high-performance and cost-effective battery technologies is crucial for storing and utilizing intermittent renewable energy. Aqueous iron-ion batteries (AIBs) constructed using low-cost iron salts hold promise in energy storage strategies but are constrained by the complex design and construction of cathode materials. Here, we report a one-step synthesis of carbon nanodots as conductive substrates for cathode-free aqueous iron-ion batteries, enabling the efficient deposition of hydroxyl iron oxide and enhanced ion storage. Scanning electron microscopy (SEM), X-ray diffraction (XRD), and Raman analyses confirm the effective deposition of hydroxyl iron oxide, ensuring the achievement of a maximum capacity of 0.43 mAh cm −2 . The designed cathode-free aqueous iron-ion battery demonstrates a long cycling life of up to 2000 cycles, representing a new direction for the development of aqueous iron-ion batteries.

Aqueous zinc ion batteries (ZIBs) have been considered promising energy storage systems due to their excellent electrochemical performance, environmental toxicity, high safety and low cost. However, uncontrolled dendrite growth and side reactions at the zinc anode have seriously hindered the development of ZIBs. Herein, we prepared the carbon nanoparticles layer coated zinc anode with (1 0 3) crystal plane preferential oriented crystal structure (denoted as C@RZn) by a facile one-step vapor deposition method. The preferential crystallographic orientation of (1 0 3) crystal plane promotes zinc deposition at a slight angle, effectively preventing the formation of Zn dendrites on the surface. In addition, the hydrophobic layer of carbon layer used as an inert physical barrier to prevent corrosion reaction and a buffer during volume changes, thus improving the reversibility of the zinc anode. As a result. the C@RZn anode achieves a stable cycle performance of more than 3000 h at 1 mA cm −2 with CE of 99.77 % at 5 mA cm −2 . The full battery with C@RZn anode and Mn-doped V 6 O 13 (MVO) cathode show stability for 5000 cycles at the current density of 5 A g −1 . This work provides a new approach for the design of multifunctional interfaces for Zn anode.

The aqueous Zn-ion batteries (AZIBs) have been deemed as one of the most promising energy storage devices owing to their high safety, low cost, and environmental benignity. Nevertheless, the severe corrosion of zinc metal anode and side reactions between the anode and electrolyte greatly hinder the practical application of AZIBs. To address above-mentioned issues, herein, a nano-CaSiO3 layer was coated on the surface of Zn metal anode via the solution casting method. Results showed that this hydrophobic coating layer could effectively inhibit the direct contact of Zn metal anode with electrolyte, suppressing its corrosion and side reactions during Zn deposition/stripping. When applied in symmetrical cells, the nano-CaSiO3 coated Zn (CSO-Zn) electrode exhibited much longer cycle life than bare Zn electrode. Moreover, with this nano-CaSiO3 modified Zn anode, both vanadium-based and manganese-based full cells depicted excellent capacity retention. This nano-CaSiO3 coating layer provides a good choice for improving the stability of Zn metal anode for high-performance AZIBs.

A low-cost and eco-friendly system based on a manganese-based complex cathode and zinc anode was demonstrated. The cathode is able to reversibly (de-)insert Zn2+ ions, providing a high capacity of 248 mA h g−1 at 0.1 A g−1. Ex situ TEM and XRD were utilized to determine the electrochemical mechanism of this high capacity cathode. Moreover, the contribution of pre-added Mn2+ in electrolyte to the capacity was revealed, and nearly 18.9% of the capacity is ascribed to the contribution of pre-added Mn2+. With the help of additive, this aqueous rechargeable battery shows outstanding electrochemical property. Its cycling performance is good with 6% capacity loss after 2000 cycles at 4.0 A g−1, highlighting it as a promising system for aqueous rechargeable battery applications.

The performance of small wearable or robotic devices is limited by the energy and power density of batteries. We present a rechargeable aqueous gel-type AgO-Zn battery, with a power density of 17.9 W/cm 3 and an energy density of 624 mWh/cm 3 at 0.2C and 358 mWh/cm 3 at 50C. We designed a multilayered fractal ion-channel structure for the long, fibrous AgO electrode using a twisting method. A prototype headband of 2 cm × 25 cm woven with the fibrous batteries was tested. With a power output of >4 W, the headband battery can extend the operation time of commercial augmented reality glasses from 2 h to over 12 h. Prototype batteries of different shapes using this design were made, including a carrying bag that works as a power bank for a phone and batteries for a small robotic spider and a robotic bird.

Vanadium dioxide (VO 2 ) material has been deemed as a potential anode candidate for aqueous lithium-ion batteries. Among its diversified polymorphs, the latest discovered VO 2 (D) receives the fewest reports on its application in energy storage. Herein, we successfully utilized a template-free solvothermal method to prepare VO 2 (D) submicron-spherical hierarchical structures, constructed with colibacillus-like nanorods . The VO 2 (D) submicron-spheres were applied as an active anode material into the aqueous lithium-ion battery, which exhibited suitable working potential. Furthermore, VO 2 (D)-based full cell with LiMn 2 O 4 as the cathode demonstrated high discharge capacity, good rate capability, and excellent cycling stability. The structural evolution, valence states of the VO 2 (D) electrode, and impedance variation of the full cell during cycling were investigated. The work reveals the potential of VO 2 (D) as a novel anode material for aqueous lithium-ion batteries.
