Flexible zinc-ion batteries with hydrogel electrolytes are the most perspective energy-storage systems for wearable applications because of their low cost, safety, abundant zinc reserves, and environmental compatibility. Hydrogel electrolytes have been shown to mitigate the growth of zinc dendrites compared with liquid electrolytes, but dendrites remain the main issue limiting the lifespan of flexible batteries. The relationship between structural and mechanical properties of hydrogels and dendrite growth is unclear, which hinders the efficient development of long-life flexible batteries. Herein, the impact of the microstructure and mechanics of hydrogels on the morphology of zinc deposition was investigated systematically, as well as the influence of current density. Hydrogels with lower porosity allowed for denser zinc plating during initial and long-term cycles since their high Young's modulus and the uniform distribution of micropores led to dendrite suppression by mechanical pressure and regulated ion transport, respectively. However, hydrogel electrolytes with higher porosity resulted in higher stability after long-term cycles because of enhanced mechanical recovery and because the voids generated between the hydrogel and electrode during electroplating and stripping were recovered. Besides, with increasing current density, the deposition layer became thicker and more uneven, thereby reducing the lifetime of zinc batteries. Our study depicts the desired microstructure and mechanical features of hydrogel electrolytes, and could pave the way for the development of flexible long-life zinc-ion batteries.

Zinc metal is recognized as the most promising anode for aqueous energy storage but suffers from severe dendrite growth and poor reversibility. However, the coulombic efficiency lacks specificity for zinc dendrite growth, particularly in Zn||Zn symmetric cells. Herein, a novel indicator ( f D ) based on the characteristic crystallization peaks is proposed to evaluate the growth and distribution of zinc dendrites. As a proof of concept, triethylenetetramine (TETA) is adopted as an electrolyte additive to manipulate the zinc flux for uniform deposition, with a corroborating low f D value. A highly durable zinc symmetric cell is achieved, lasting over 2500 h at 10 mA cm −2 and 400 h at a large discharge of depth (10 mA cm −2 , 10 mAh cm −2 ). Supported by the low f D value, the Zn||TETA-ZnSO 4 ||MnO 2 batteries overcome the sudden short circuit and fast capacity fading. The study provides a feasible method to evaluate zinc dendrites and sheds light on the design of highly reversible zinc anodes.

Aqueous rechargeable zinc ion batteries are regarded as a competitive alternative to lithium-ion batteries because of their distinct advantages of high security, high energy density, low cost, and environmental friendliness. However, deep-seated problems including Zn dendrite and adverse side reactions severely impede the practical application. In this work, we proposed a freestanding Zn-electrolyte interfacial layer composed of multicapsular carbon fibers (MCFs) to regulate the plating/stripping behavior of Zn anodes. The versatile MCFs protective layer can uniformize the electric field and Zn 2+ flux, meanwhile, reduce the deposition overpotentials, leading to high-quality and rapid Zn deposition kinetics. Furthermore, the bottom-up and uniform deposition of Zn on the Zn-MCFs interface endows long-term and high-capacity plating. Accordingly, the Zn@MCFs symmetric batteries can keep working up to 1500 h with 5 mAh cm −2 . The feasibility of the MCFs interfacial layer is also convinced in Zn@MCFs||MnO 2 batteries. Remarkably, the Zn@MCFs||α-MnO 2 batteries deliver a high specific capacity of 236.1 mAh g −1 at 1 A g −1 with excellent stability, and maintain an exhilarating energy density of 154.3 Wh kg −1 at 33% depth of discharge in pouch batteries.

Zinc-based flow batteries (ZFBs) have shown great promise as large-scale energy storage devices due to their high energy density, low cost and environmental friendliness. In order to prevent Zinc (Zn) dendrites growth and side-reactions which result in poor cell performance and short cycle life, low-cost potassium chloride is often utilized as the supporting electrolyte to enhance the Zn redox reversibility. In this work, the effect of this supporting electrolyte is studied. Experimental characterizations reveal that cation-type Zn(H 2 O) 5 Cl + solvation structure could transform to an anion-type water-free solvation structure ZnCl 4 2− by adding more chloride salt. The electrostatic shielding effect of potassium ion and anion-type water-free ZnCl 4 2− could homogenize Zn ion flux to achieve a dendrite-less morphology during the reduction process. The improved negolyte enables ZFBs to run for 300 h with a high energy efficiency (>83 %) at 40 mA cm −2 , 20 mAh cm −2 . Besides, the hydrogen-bond network in negolyte is reshaped, expanding the operating temperature range of the system. This work determines the effect of supporting electrolyte in Zn negolyte, which can guide the design of electrolyte and promote further research on Zn electrode in ZFBs.

Zinc metal is a promising choice as a high-capacity and cost-effective anode for aqueous zinc-based batteries. However, it faces challenges related to low cycling stability and poor reversibility due to parasitic reactions and the growth of zinc dendrites. In this study, a solution is proposed by introducing a conductive Ti 4 O 7 layer on the zinc anode to enhance electrode stability. The Ti 4 O 7 layer serves a dual purpose, effectively preventing spontaneous corrosion of the zinc anode in the electrolyte, thereby inhibiting the hydrogen evolution reaction and the generation of byproducts. Simultaneously, it promotes Zn nucleation and ensures a uniform electric field distribution, resulting in homogeneous Zn plating and stripping compared to using a bare zinc anode. Consequently, the Ti 4 O 7 -coated Zn anode experiences a significant reduction in over-potential, demonstrating long-term stability and dendrite-free behavior. This outcome ensures low polarization potential and high cycling stability in zinc-ion batteries. The work underscores the potential of conductive oxides in the development of stable metal electrodes.

Graphite was reported by J.O. Besenhard as the reservoir for alkali ions in 1974. The booming period of lithium-ion batteries arrived after the graphite patent issued by Sony Co. in 1991. The flourish development is due to the address of lithium dendrite issue through the substitution from lithium metal to graphite. Currently, the zinc dendrite formation in zinc-ion batteries is one of the major issues. Herein, we fabricate a zinc-ion full battery by replacing zinc metal with organic quinone , which is a zinc dendrite free material. This novel zinc-ion full battery exhibits excellent cycling stability with capacity retention of 94.4% and high specific capacity of 189.5 mA h g −1 after 500 cycles. Ascribed to the low cost of quinone and long cycle performance, this work could inaugurate a new era for rechargeable aqueous zinc-ion batteries.

The energy density of aqueous reachable batteries (ARBs) is limited by the output voltage in the aqueous electrolyte. Herein, low-cost aqueous hybrid electrolytes composed of ZnSO 4 and K 2 SO 4 dual salts effectively improve the output voltage and suppress the zinc dendrites. The aqueous full cells assembled with potassium zinc hexacyanoferrate (KZnHCF) cathodes and zinc foil anodes reach an output voltage of 1.92 V and an energy density of 107.6 Wh kg −1 . It is demonstrated the reversible insertion/extraction of K + at the cathodes and uniform zinc deposition/striping at the anode in hybrid electrolyte via a series in-situ and ex-situ investigation. The dual salt electrolyte can not only satisfy the reversible capacitive dominated process at the cathodes but also suppress the zinc dendrite. Density functional theory (DFT) calculation demonstrates the K + preferential intercalation mechanism of KZnHCF in hybrid electrolyte and the inhibition effect of K + insertion on Zn 2+ insertion. This strategy presents a promising approach for development of high performance and low-cost aqueous electrolyte.

Commercial 3D zinc foam anodes with high deposition space and ion permeation have shown great potential in aqueous ion batteries. However, the local accumulated stress from its high-curvature surface exacerbates the Zn dendrite issue, leading to poor reversibility. Herein, we have employed zincophilic N-doped carbon @ Sn composites (N-C@Sn) as nano-fillings to effectively release the local stress of high curvature surface of 3D Zn foams toward dendrite-free anode in aqueous zinc ion battery (AZIB). These electronegative and conductive N-C@Sn nano-fillings as supporters can provide a highly zincophilic channel for initial Zn nucleation and reduce local current density for regulating Zn deposition. Uniform Zn deposition further assists homogenous stress distribution on the platting surface, which gives a positive feedback loop to improve anode reversibility. As a result, zinc foam with N-C@Sn composite (ZCSn Foam) symmetric cell achieves a long cycle lifespan of 1100h at 0.5 mA cm −2 , much more than that of Zn Foam (∼80 h lifespan). The full cell ZCSn Foam||MnO 2 exhibits remarkable reversibility with 67% retention after 1000 cycles at 0.8 A g −1 and 76% after 1600 cycles at 2 Ag −1 . This 3D-constructing strategy may offer a promising and practical pathway for metal anode application.

Zinc corrosion, hydrogen evolution reaction, uneven deposition, and dendrite growth on the zinc anodes are the key factors restraining the electrochemical performance and cycling stability of the aqueous zinc-ion batteries. In this study, learned from the synial membrane, a tiny amount of natural amino acid β-alanine (β-Ala, 0.089 wt %) was introduced as the additive in ZnSO4 electrolyte for strengthening the kinetics of the zinc anode as well as enhancing the performance of zinc ions batteries. A number of modern surface techniques and surface electrochemical analyses were employed to reveal the fundamental reasons for the strengthened zinc anode by β-Ala in ZnSO4 electrolyte. The results show that β-Ala could be adsorbed on zinc electrode surface through intermolecular chelation, which might regulate the chemical environments of the electrolyte and promote uniform deposition of zinc ions. Hence, the β-Ala adsorption film on zinc electrode could suppress the hydrogen evolution reaction and the formation of zinc dendrites, thereby significantly improving the deposition/stripping process of the zinc anode. In particular, the strong hydrogen bonding could restrain the migration of H2O molecules approaching the zinc anode surface, preventing the invasion of water to the zinc electrode surface. Therefore, the addition of dilute β-Ala in the ZnSO4 electrolyte might remarkably prolong the life span of Zn||Zn symmetric batteries to 5000 h under 1 mA cm–2 and 1 mAh cm–2, and to 450 h under 5 mA cm–2 and 3 mAh cm–2 at 298 K, which is much longer than the zinc–zinc symmetric cells including the bare ZnSO4 electrolyte (only 95 h at 5 mA cm–2 and 3 mAh cm–2, and 200 h at 1 mA cm–2 and 1 mAh cm–2). Furthermore, β-Ala was found to significantly improve the cycling stability of Zn||Cu asymmetric cells and Zn||V2O5 full cells. This study provides an effective method for engineering electrolytes to inspire rechargeable zinc-ion batteries by selecting ideal natural biomolecules as the electrolyte additives.

Zn-based electrochemical energy storage (EES) systems have received tremendous attention in recent years, but their zinc anodes are seriously plagued by the issues of zinc dendrite and side reactions (e.g., corrosion and hydrogen evolution). Herein, we report a novel strategy of employing zincophilic Cu nanowire networks to stabilize zinc anodes from multiple aspects. According to experimental results, COMSOL simulation and density functional theory calculations, the Cu nanowire networks covering on zinc anode surface not only homogenize the surface electric field and Zn 2+ concentration field, but also inhibit side reactions through their hydrophobic feature. Meanwhile, facets and edge sites of the Cu nanowires, especially the latter ones, are revealed to be highly zincophilic to induce uniform zinc nucleation/deposition. Consequently, the Cu nanowire networks-protected zinc anodes exhibit an ultralong cycle life of over 2800 h and also can continuously operate for hundreds of hours even at very large charge/discharge currents and areal capacities (e.g., 10 mA cm −2 and 5 mAh cm −2 ), remarkably superior to bare zinc anodes and most of currently reported zinc anodes, thereby enabling Zn-based EES devices to possess high capacity, 16,000-cycle lifespan and rapid charge/discharge ability. This work provides new thoughts to realize long-life and high-rate zinc anodes.

Dendrites and side reactions of Zn anodes severely restrict the application of aqueous Zn-based batteries for grid-scale energy storage. While surface/interface modification strategies have shown some progress in improving Zn anode reversibility, they still fall short in addressing the overall regulation and intrinsic mechanisms from the bulk-phase perspective. Herein, a bulk-phase composite Zn/CNTs anodes fabricated by a powder-metallurgy-based strategy is introduced. Benefiting from the regulation of grain boundary engineering on local electric conductivity, electric field distributions, and Zn atom absorption energy, the Zn/CNTs anodes effectively suppress dendrite growth and enhance corrosion resistance during Zn stripping/plating cycles. Symmetrical cells equipped with Zn/CNT4 anodes exhibit extended cycling stability with minimal voltage hysteresis (only 22 mV). Furthermore, the full cells incorporating Zn/CNT4 with commercial MnO 2 demonstrate superior rate performance and specific capacitance retention after 500 h cycling. This breakthrough opens up new avenues for optimizing metallic anodes at the bulk phase level using powder metallurgy, enabling scalable manufacturing processes, and providing valuable insights for various metal anode systems.

In this study, a low-cost and friendly compound diazolidinylurea carrying a number of heteroatoms and inter/intra hydrogen bonding, a derivative of urea (DU), efficiently strengthened aqueous zinc ions batteries (AZIBs) in ZnSO4 electrolyte. The influence of DU on the zinc anode in the 2 M ZnSO4 electrolyte was fully studied by various surface chemistry and electrochemistry means. It is demonstrated that the super low concentration of DU (2 mM, 0.00556 wt %) could inhibit the formation of zinc dendrites, zinc corrosion, and the hydrogen evolution reaction during the constant current cycling of water system ZIBs, which thus enabled symmetric zinc–zinc batteries to reach a cycle life of 7336 h (nearly 306 days) under 1 mA·cm–2, 1 mA h·cm–2 at 25 °C and 426 h (nearly 18 days) at 55 °C, and inspired zinc–manganese full battery to maintain a capacity retention rate of more than 52% after cycling for 1000 cycles under a current of 2 A·g–1. These results are much superior over zinc ion cells based on the blank ZnSO4 batteries. Even if the Zn–Cu half cells including the DU/2 M ZnSO4 electrolyte were also more pronounced than those with the bare ZnSO4 electrolyte. The maximum corrosion inhibition efficiency of the DU for the zinc electrode in ZnSO4 solution exceeded 82%. Hence, the suppression of zinc corrosion and parasitic side reactions, as well as the formation and growth of zinc dendritic crystals by the addition of DU in zinc sulfate electrolyte, played a central role in intensifying aqueous zinc ion batteries.
