“…The remarkable cycling life and excellent reversibility of Zn-SHn outperform other reported strategies for construction of a Zn protective layer (Figure S20, Supporting Information). [13,17,18,26,41,46,[49][50][51][52][53][54][55][56][57][58] To evaluate the feasibility of Zn-SHn in practical AZIB application, NaV 3 O 8 •1.5H 2 O (NVO) was selected as the cathode material, which can be synthesized via a facile hydrothermal method. [59] The XRD pattern of NVO matches well with P2 1 /m space group (JCPDS 16-0616) (Figure S21a, Supporting Information), where sodium ions serve as pillars between the V 3 O 8 layers to stabilize the structure.…”

Furthermore, such a hydrogel layer chemically bonded on the Zn surface possesses an anti-catalysis effect, which effectively suppresses both the hydrogen evolution reaction and formation of Zn dendrites. As a result, stable and reversible Zn stripping/plating at various currents and capacities is achieved. A full cell by pairing the Zn-SHn anode with a NaV 3 O 8 •1.5 H 2 O cathode shows a capacity of around 176 mAh g −1 with a retention around 67% over 4000 cycles at 10 A g −1 . This polyanionic hydrogel film protection strategy paves a new way for future Zn-anode design and safe aqueous batteries construction.

“…The extra peaks located at the low angles might be the by‐product of zinc hydroxide sulfate hydrate, which is hard to be avoided. [ 47 ] Density functional theory (DFT) calculations are carried out to gain deep insights into the influence of Cu single atoms on the Zn deposition. We construct the adsorption models of the interaction between Zn and the hosts, including ZIF‐L, CuZIF‐L, and CuZn 3 (Figure S14, Supporting Information).…”

Aqueous Zn metal batteries (AZMBs) have been considered as a promising alternative to the existing Li‐ion batteries. Nevertheless, the large‐scale application of the AZMBs is restricted by the dendrite formation and side reactions within the Zn metal anodes (ZMAs) during cycling. Herein, an atomically dispersed Cu in leaf‐like Zn‐coordinated zeolitic imidazolate framework (ZIF‐L) nanoflakes on Ti mesh (CuZIF‐L@TM) as ZMA host is developed. The 3D conductive network formed by the interconnected ZIF‐L nanoflakes can reduce the local current density and homogenize the electric field distribution. Moreover, experimental data and theoretical calculations reveal the Cu single atoms within the ZIF‐L can serve as the zincophilic sites to facilitate the Zn deposition. As expected, the CuZIF‐L@TM host enables a homogeneous Zn deposition on the surface without dendrites. The resultant CuZIF‐L@TM/Zn electrode shows stable Zn plating/stripping over 1100 h at 1 mA cm−2 with a low voltage hysteresis of about 50 mV. As a proof of concept, a full cell based on the designed CuZIF‐L@TM/Zn anode shows a stable cycling performance over 1000 cycles.

“…[ 100 ] The introduced ZIF‐8 layer could regulate Zn nucleation to achieve uniform Zn deposition. In addition to the aforementioned examples, other in situ formed protective films were also demonstrated to be effective in the inhibition of zinc dendrites and side reactions, including TiN, [ 101 ] ZnSe, [ 102 ] Zn 3 (PO 4 ) 2 , and ZnF 2 (ZCS). [ 103 ] Note that, despite their better affinity to Zn than the ex‐situ grown ones, the stability of the protective layer also needs to be considered, such as the possible decomposition or dissolution.…”

Rechargeable aqueous zinc-based batteries (AZBs) have received massive attention as promising contenders for the future large-scale energy storage due to their low cost, inherent safety, and abundant resources. However, the insufficient energy density and poor stability have become the key to hinder their further application. As is well known, the energy densities (E, Wh kg −1 ) of AZBs are determined by the specific capacity (mAh g −1 ) and output voltage (V). Given the fixed redox potential and capacity of the Zn metal anode, the energy density of AZBs is mainly determined by the cathode material, and the rich material systems of the cathode provide more possibilities to this field. Meanwhile, the methods to improve the stability and performance of the Zn anodes have gained more and more attention due to the severe Zn dendrite growth that can pierce the separator and lead to short-circuiting of the cell. Therefore, in this review, we comprehensively summarize the rational design methods in optimizing the cathode, anode, and device architecture, and classic examples of each catalogue are discussed in details as well. Last, the issues and outlook for further development of high performance AZBs are also presented.
