Abstract

Aqueous zinc anodes have attracted the attention of many researchers owing to their high safety, low cost, and high theoretical specific capacity. However, its practical application is severely limited by the dendrite growth on zinc anode. Herein, we develop an intrinsically zincophobic barium-titanate protective layer with a porous structure to suppress the zinc dendrite formation by homogenizing the ion distribution on the anode surface, increasing the nucleation sites, and limiting the irregular zinc growth. Based on these synergistic effects, the coated zinc anode can exhibit long cycle life (840 h at 0.5 mA/cm² for 0.5 mAh/cm²) and low voltage hysteresis (36 mV). This work can provide a feasible direction for the design of intrinsically zincophobic coating materials to uniformize the zinc stripping and plating.

Polycarbonyl polymer with zincophilic sites as protective coating for highly reversible zinc metal anodes
2024, Journal of Colloid and Interface Science
The Zn anode of aqueous zinc ion batteries (AZIBs) have suffered from a series of rampant side reactions such as dendrite growth and corrosion, which seriously affect the reversibility and stability of Zn anodes. Herein, a polycarbonyl polymer poly(1,4,5,8-naphthalene tetracarboxylic anhydride anthraquinone) imine (PNAQI) as the protective coating is synthesized through a simple solvothermal method with the raw materials of the equimolar 1,4,5,8-naphthalenetetracarboxylic dianhydride (NTCDA) and 2, 6-aminoanthraquinone (2,6-DAAQ). A series of characterizations such as contact angle measurement and ex-situ XRD analysis confirm that it can effectively prevent some side reactions. Moreover, CO on PNAQI can regulate the uniform distribution of zinc, thereby preventing the occurrence of zinc dendrites. Finally, the PNAQI@Zn//PNAQI@Zn symmetrical cell demonstrates a long cycle life exceeding 1000 h at current density of 1.0 mA cm⁻² and a capacity of 1.0 mAh cm⁻². The result significantly outperforms the cycling performance of the cell with bare zinc anode. Especially, the full battery of PNAQI@Zn//NH₄V₄O₁₀ demonstrates an excellent capacity retention and prolonged cycle life (96.9 mAh/g after 1000 cycles at 1.0 A/g) compared to Zn//NH₄V₄O₁₀. This work provides an effective, simple and low-cost solution for developing high-performance AZIBs.
A self-repairing polymer-inorganic composite coating to enable high-performance Zn anodes for zinc-ion batteries
2023, Chinese Chemical Letters
There are some critical issues hindering the practical applications of aqueous zinc-ion batteries (ZIBs), although they possess high safety and low cost as one of promising energy storge devices, such as the Zn dendrite growth and the by-product of Zn₄SO₄(OH)₆·xH₂O (ZHS) resulted from some side reactions in a mild electrolyte. Herein, a compact and self-repairing solid electrolyte interface (SEI) film, as labeled the PVDF-Zn(TFSI)₂-ZHS coating [The PVDF and Zn(TFSI)₂ are polyvinylidene fluoride and zinc bis(trifluoromethanesulfonyl)imide, respectively], which turns the in-situ generated ZHS into a beneficial ingredient onto the pre-coated PVDF-based composite coating layer containing Zn(TFSI)₂, was designed and fabricated by a simple doctor blade method. It is shown that the SEI layer can effectively isolate Zn from the electrolyte and homogenize the Zn²⁺ flux, and thus effectively suppress side reactions and dendrites growth. Benefiting from the hybrid SEI layer, a symmetric cell exhibits a high cycling stability over 750 h at 2.0 mA/cm² and 2.0 mAh/cm², and meanwhile, a full-cell, coupled with K⁺ pre-intercalation α-MnO₂ (KMO) cathode, displays excellent rate performance, stable coulombic efficiency and an acceptable cycle life. This work provides a feasible approach for simple and scalable modification of Zn anodes to achieve high performance.
Towards a high-performance anode for zinc metal batteries: A tri-functional nitrogen-defective graphitic carbon nitride material for anode protection
2023, Journal of Colloid and Interface Science
As an important potential candidate for large-scale energy storage, rechargeable zinc metal batteries have become a research hotspot. Zn metal anodes are an extremely crucial component of rechargeable Zn metal batteries. However, the Zn dendrites, the evolution of hydrogen and side reactions on the surface of the Zn metal anodes severely hinder its commercial use. Here, we report a modified Zn metal anode with a layer of nitrogen-defective graphitic carbon nitride (NDCN) nanosheets coated onto a commercial Zn foil by a simple spraying method. The NDCN coating on the anode’s surface not only provides zincophilic sites, but also drives the deposition of zinc with a particular crystallographic orientation. At the same time, the formation of zinc dendrites and the evolution of hydrogen were suppressed, which enhanced the reversibility of the anode. Thus, the symmetric cells with the NDCN-protected zinc foil (NDCN@Zn) electrodes remained stable for 2000 h at a current density of 5 mA cm⁻². More importantly, the long-term cycling performance of the full cell tested at 1 A g⁻¹ retained approximately 88 % of its capacity even after 2300 cycles. This simple but effective method will provide a reference for future studies on protecting the anodes of zinc metal batteries.
Tailoring zincophilicity via amorphous Se-rich selenides coating for stable Zn anode
2023, Chemical Engineering Journal
Aqueous Zn-ion batteries (AZIBs) are being extensively studied for promising energy storage applications owing to their advantages of excellent safety, and high theoretical capacity. Nevertheless, the Zn anode in electrolytes obstinately suffers from irreversibility issues, e.g., the low coulombic efficiency and dendrite growth during cycling. Thus, it remains a severe challenge to obtain high cycling stability of Zn anodes. Tuning zincophilicity has been a high-interest topic as a class of Zn anode optimization. Herein, tailoring zincophilicity via amorphous Se-rich selenides coating for a stable Zn anode is reported. The Zn foils were surface-modified by coating with intrinsic zincophobic selenide (i.e., WSe₂ and MoSe₂, resulting in WSe₂-Zn and MoSe₂-Zn, respectively). Interestingly, a Se-rich layer with a particular amorphous structure was manufactured on the Zn anode. The enrichment of Se was electrochemically induced to form ZnSe, which improves zincophilicity of the Zn anode and provides nucleation sites for Zn ions. Accordingly, homogeneous deposition and exfoliation of Zn ions were promoted, and the growth of Zn dendrites during cycles was inhibited. Along with suppressed side-product generation, the outputs of AZIBs with modified electrodes were vastly improved. The symmetric batteries with selenides exhibit a low polarization and prolonged life over 1700 h. Besides, it is shown that the specific capacity and stability of the full batteries using sodium vanadate as cathodes are remarkably enhanced by selenide modification. Further, when assembled with Mn-based cathodes, good capacity retention (77.5% for WSe₂-Zn, 74.7% for MoSe₂-Zn, and 49.5% for pristine Zn) at 2 A/g was achieved over 3500 cycles. A facile route to tune intrinsic zincophobicity into zincophilicity is demonstrated, which brings about massive opportunities for developing high-performance electrode materials for AZIBs.
Ultrasound-induced elevation of interlayer spacing and conductivity of CoNi hydroxides for high-performance Ni–Zn batteries
2023, Chinese Chemical Letters
Nickel–zinc (Ni–Zn) batteries hold a lot of promise for energy storage thanks to their high output voltage, plentiful Zn supply, and low toxicity. Achieving the facile preparation of high-performance cathodes at ambient temperature remains a challenge, it is however essential for practical applications. Here, in the present study, an efficient ultrasound-assisted one-step fabrication of CoNi double hydroxide (UA-CoNi DH) microspheres at room temperature that performs well as a cathode for Ni–Zn batteries was proposed. This designed ultrasound-assisted method induces the formation of metal double hydroxide with an elevation of interlayer spacing and bulk conductivity while maintaining the structure features of CoNi DH prepared without ultrasound assistance. As a result, the UA-CoNi DH as an electrode material displays highly enhanced electrochemical properties relative to CoNi DH prepared without ultrasound assistance. Benefitting from the improved performance of our UA-CoNi DH electrode, the Ni–Zn battery with UA-CoNi DH as the cathode (UA-CoNi DH//Zn) delivers a good specific capacity (202.36 mAh/g) and rate performance (70.49% capacity maintained at a 10-fold higher current), presenting more than 71.61% and 21.99% improvement relative to the CoNi DH//Zn battery, respectively. This work offers guidelines for constructing high-performance Ni–Zn battery cathodes in an open environment.
Calcium-organic frameworks cathode for high-stable aqueous Zn/organic batteries
2023, Chinese Chemical Letters
Rechargeable aqueous zinc-ion batteries (AZIBs) are attracting tremendous attention because of their intrinsic merits such as high safety and low cost. Cathode plays a critical role in enhancing the electrochemical performance of AZIBs. However, it is difficult to design a robust and high-efficiency cathode material and further implement the commercialization of AZIBs. Metal-organic frameworks (MOFs) electroactive compounds are attractive to serve as the cathode of AZIBs due to their unique porosity and crystal structures, resource renewability and structural diversity. In this work, a calcium-pure terephthalates acid framework (Ca-PTA·3H₂O) was synthesized by facile hydrolysis and cationic exchange method, then explored as a novel cathode for AZIBs. The results highlight a high specific capacity of 431 mAh/g (0.51 mAh/cm²) at a current density of 50 mA/g, and excellent cycle performance with capacity retention of ∼90% after 2700 cycles at 500 mA/g. The following up characterizations investigate the reversible zinc storage mechanism in detail. This experiment made a specific contribution to the exploration of the new MOF as a competitive cathode for AZIBs.
