Aqueous rechargeable Zn metal batteries have attracted widespread attention due to the intrinsic high volumetric capacity, low cost, and high safety. However, the low Coulombic efficiency and limited lifespan of Zn metal anodes resulting from uncontrollable growth of Zn dendrites impede their practical application. In this work, a 3D interconnected ZnF2 matrix is designed on the surface of Zn foil (Zn@ZnF2) through a simple and fast anodic growth method, serving as a multifunctional protective layer. The as‐fabricated Zn@ZnF2 electrode can not only redistribute the Zn2+ ion flux, but also reduce the desolvation active energy significantly, leading to stable and facile Zn deposition kinetics. The results reveal that the Zn@ZnF2 electrode can effectively inhibit dendrites growth, restrain the hydrogen evolution reactions, and endow excellent plating/stripping reversibility. Accordingly, the Zn@ZnF2 electrode exhibits a long cycle life of over 800 h at 1 mA cm−2 with a capacity of 1.0 mAh cm−2 in a symmetrical cell test, the feasibility of which is also convincing in Zn@ZnF2//MnO2 and Zn@ZnF2//V2O5 full batteries. Importantly, a hybrid zinc‐ion capacitor of the Zn@ZnF2//AC can work at an ultrahigh current density of ≈60 mA cm−2 for up to 5000 cycles with a high capacity retention of 92.8%.

“…The carbon-based materials such as CNTs, [241] rGO, [242] and carbon black [243] have also been proposed as the suitable candidates for the coating of Zn anode to minimize the issues associated with Zn. The experimental and theoretical studies show that the CNT coating completely inhibits the dendrite formation due to its charge redistribution effect on overpotential.…”

The growing demand for the renewable energy storage technologies stimulated the quest for efficient energy storage devices. In recent years, the rechargeable aqueous zinc-based battery technologies are emerging as a compelling alternative to the lithium-based batteries owing to safety, eco-friendliness, and cost-effectiveness. Among the zinc-based energy devices, rechargeable zinc-ion batteries (ZIBs) are drawing considerable attention. However, they are plagued with several issues, including cathode dissolution, dendrite formation, etc.. Despite several efforts in the recent past, ZIBs are still in their infant stages and have yet to reach the stage of large-scale production. Finding stable Zn 2 + intercalation cathode material with high operating voltage and long cycling stability as well as dendrite-free Zn anode is the main challenge in the develop-ment of efficient zinc-ion storage devices. This Review discusses the various strategies, in terms of the engineering of cathode, anode and electrolyte, adopted for improving the charge storage performance of ZIBs and highlights the recent ZIB technological innovations. A brief account on the history of zinc-based devices and various cathode materials tested for ZIB fabrication in the last five years are also included. The main focus of this Review is to provide a detailed account on the rational engineering of the electrodes, electrolytes, and separators for improving the charge storage performance with a future perspective to achieving high energy density and long cycling stability and large-scale production for practical application.

Aqueous zinc‐based rechargeable batteries are considered to be one of the most promising new energy storage systems due to their unique advantages (e.g., low cost, high safety, environmental friendliness, and high energy density). However, the formation of zinc dendrites at the anode during the operation can puncture the separator and even cause short circuit of batteries, which is one of the serious problems in Zn‐based batteries. Therefore, understanding the growth process of dendrites and suppressing the formation of zinc dendrites are necessary for the further development and large‐scale applications of Zn‐based batteries. Herein, the growth mechanism and the influence factors of zinc dendrites are first introduced in detail by combining the experimental and theoretical results. Moreover, the effective strategies for suppressing dendrites through micronanostructured design are summarized, including surface modification, alloying, and substrate selection/porous structure engineering. In the end, the challenges in the further development of high‐performance dendrite‐free zinc anode are discussed, and the research frontiers trends are prospected as well. It is aimed to shed light on the rational design and structure tuning of high‐performance zinc electrode materials for advanced zinc‐based secondary batteries for clean energy storage technologies.
