Aqueous zinc-ion batteries (AZIBs) have gained significant attentions for their inherent safety and cost-effectiveness. However, challenges, such as dendrite growth and anodic corrosion at the Zn anode, hinder their commercial viability. In this paper, an organic−inorganic coating layer (Nafion−TiO 2 ) was introduced to protect the Zn anode and electrolyte interface. Briefly, Nafion effectively shields against the corrosion from water molecules through the hydrophobic wall of −CF 3 and guided zinc deposition from the −SO 3 functional group, while TiO 2 particles with a higher Young's modulus (151 GPa vs 120 GPa from Zn metal) suppress the zinc dendrite formation. As a result, with the protection of Nafion−TiO 2, the symmetrical Zn∥Zn battery shows an improved cycle life of 1,750 h at 0.5 mA cm −2 , and the full cell based on Zn∥MnO 2 shows a long cycle life over 1,500 cycles at 1 A g −1 . Our research offers a novel approach for protecting zinc metal anodes, potentially applicable to other metal anodes such as those in lithium and sodium batteries.

“…Inorganic coatings, including CaCO 3 , ZnO, and ZnF 2 can guide homogeneous Zn 2+ -ion flux, contributing to the smooth Zn deposition. [31][32][33][34][35] Unfortunately, they have to be used together with binders to obtain compact layer because of their brittle nature. Polymer coatings, like polyacrylonitrile (PAN) possess superior elasticity, which can accommodate the volume change during battery cycling.…”

Aqueous Zn‐based batteries (AZBs) have appealed numerous attentions in the energy storage field due to their low cost, environmental friendliness and high safety. However, the Zn metal anode faces severe challenges of short cycle life because of the dendrite growth and side reactions, which hinders the practical application of AZBs. Herein, an artificial coating layer of cyclized polyacrylonitrile (cPAN) is designed on the Zn anode through spin‐coating and thermal treatment. The cPAN layer possesses abundant N‐containing groups and delocalized π‐conjugation structure, which endows the Zn anode with low nucleation barrier and homogeneous electric field. Benefiting from these synergetic advantages, the nucleation overpotential of Zn is remarkably decreased. Furthermore, no obvious byproduct is observed on the cPANZ‐Zn after cycling. As a result, the resultant cPANZ‐Zn anode delivers a long lifespan of 600 h and high reversibility. cPANZ‐Zn||MnO2 full cells are further assembled and exhibited stable cycling and high rate capability.

“…Until now, many efforts have been devoted to solving the aforementioned problems, including surface modification of Zn metal anodes [ 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 ], electrolyte optimization [ 17 , 18 , 19 ], novel separator design [ 20 ] and three-dimensional (3D) host design [ 21 , 22 , 23 , 24 ]. For example, He et al [ 25 ] deposited an ultrathin Al 2 O 3 film on the Zn anode via the atomic layer deposition method, which effectively improved the interfacial wettability of the Zn anode and thus physically suppressed the formation of Zn dendrites.…”

Aqueous Zn-ion batteries (AZIBs) are one of the most promising large-scale energy storage devices due to the excellent characteristics of zinc metal anode, including high theoretical capacity, high safety and low cost. Nevertheless, the large-scale applications of AZIBs are mainly limited by uncontrollable Zn deposition and notorious Zn dendritic growth, resulting in low plating/stripping coulombic efficiency and unsatisfactory cyclic stability. To address these issues, herein, a carbon foam (CF) was fabricated via melamine-foam carbonization as a scaffold for a dendrite-free and stable Zn anode. Results showed that the abundant zincophilicity functional groups and conductive three-dimensional network of this carbon foam could effectively regulate Zn deposition and alleviate the Zn anode’s volume expansion during cycling. Consequently, the symmetric cell with CF@Zn electrode exhibited lower voltage hysteresis (32.4 mV) and longer cycling performance (750 h) than the pure Zn symmetric cell at 1 mA cm−2 and 1 mAh cm−2. Furthermore, the full battery coupling CF@Zn anode with MnO2 cathode can exhibit a higher initial capacity and better cyclic performance than the one with the bare Zn anode. This work brings a new idea for the design of three-dimensional (3D) current collectors for stable zinc metal anode toward high-performance AZIBs.
