Rechargeable aqueous zinc ion batteries (AZIBs) with metallic Zn anodes have been regarded as attractive candidates for large‐scale energy storage systems as a result of their affordability, safety, and high energy density. However, the practical implementation of rechargeable AZIBs is still hampered severely by the poor electrochemical stability and reversibility of Zn anodes, stemming from uncontrolled dendrite growth and rampant side reactions. Due to the versatility of different components in the composite artificial interface layer (AIL), great efforts on multifunctional AILs have recently been devoted to Zn anode protection for designing durable and stable AZIBs. This review first presents a comprehensive and timely summarization on the origin and mechanism of dendrite growth and side reactions, followed by the systematic summarization of five protection mechanisms/functions of the AILs. Next, recent advances are discussed in the manner of a correlation between the combined materials/structures in composite AILs and their synergetic functionality, highlighting the critical role of functional orientation design of the composite AILs towards stable Zn anodes. Finally, perspectives and suggestions are provided for designing highly effective multifunctional composite AILs towards Zn anodes for AZIBs.

“…Due to the uniform Zn deposition and the high electrochemical stability of the Zn (002) crystal plane, the LM@Zn electrode can achieve superior side reaction resistance and cycling stability. [41][42] Figure S16 (Supporting Information) shows the SEM images of Zn fiber and LM@Zn fiber electrodes after immersing in 2 m ZnSO 4 for 5 days. The Zn fiber exhibits a rough surface covered with flake-shaped byproducts, indicating poor side reaction resistivity.…”

Electronic textiles harmoniously interact with the human body and the surrounding environment, offering tremendous interest in smart wearable electronics. However, their wide application faces challenges due to the lack of stable and stretchable power electrodes/devices with multifunctional design. Herein, we report an intrinsically stretchable liquid metal‐based fibrous anode for a stable Zn‐ion battery (ZIB). Benefiting from the liquid feature and superior deformability of the liquid metal, optimized Zn ion concentration distribution and Zn (002) deposition behavior have been observed, which results in dendrite‐free performance even under stretching. With a strain of 50%, the ZIB maintains a high capacity of 139.8 mAh cm−3 (corresponding to 83.0% of the initial value) after 300 cycles, outperforming bare Zn fiber‐based ZIB. The fibrous ZIB seamlessly integrates with sensor, Joule heater and wirelessly charging device, which provides a stable power supply for human signal monitoring and personal thermal management, holding promise for the application of wearable multifunctional electronic textiles.This article is protected by copyright.

“…Besides, the passivated surface induces inhomogeneous Zn deposition that brings the risk of dendrite growth and battery short circuit . The construction of protective layers, such as inorganics, , polymers, , alloys, , and metal–organic frameworks, − is an effective strategy to increase the reversibility of Zn anodes. They prevent the direct contact between Zn anodes and electrolytes and thus alleviate the side reactions.…”

Aqueous zinc batteries are appealing devices for cost-effective and environmentally sustainable energy storage. However, the critical issues of uncontrolled dendrite propagation and side reactions with Zn anodes have hindered their practical applications. Inspired by the functions of the rosin flux in soldering, an abietic acid (ABA) layer is fabricated on the surface of Zn anodes (ABA@Zn). The ABA layer protects the Zn anode from corrosion and the concomitant hydrogen evolution reaction. It also facilitates fast interfacial charge transfer and horizontal growth of the deposited Zn by reducing the surface tension of the Zn anode. Consequently, promoted redox kinetics and reversibility are simultaneously achieved by the ABA@Zn. It demonstrates stable Zn plating/stripping cycling over 5100 h and a high critical current of 8.0 mA cm −2 . Moreover, the assembled ABA@Zn|(NH 4 ) 2 V 6 O 16 full cell delivers outstanding long-term cycling stability with an 89% capacity retention after 3000 cycles. This work provides a straightforward yet effective solution to the key issues of aqueous zinc batteries.
