“…There are only a few publications focusing on the charge storage mechanism of poly‐anion compounds for ZIS and these publications focus mostly on phosphate materials. [ 84 ] The complexity of the electrochemical reaction lies in different insertion positions and migration pathways of Zn 2+ in poly‐anion structures. For instance, earlier studies show that Na + is first extracted from the 18e site of Na 3 V 2 (PO 4 ) (NVP), and Zn 2+ ions are subsequently inserted at both the 18e and 6b sites in NVP , a representative NASICON‐structured poly‐anion material.…”

Limited Li resources, high cost, and safety risks of using organic electrolytes have stimulated a strong motivation to develop non‐Li aqueous batteries. Aqueous Zn‐ion storage (ZIS) devices offer low‐cost and high‐safety solutions. However, their practical applications are at the moment restricted by their short cycle life arising mainly from irreversible electrochemical side reactions and processes at the interfaces. This review sums up the capability of using 2D MXenes to increase the reversibility at the interface, assist the charge transfer process, and thereby improve the performance of ZIS. First, they discuss the ZIS mechanism and irreversibility of typical electrode materials in mild aqueous electrolytes. Then, applications of MXenes in different ZIS components are highlighted, including as electrodes for Zn2+ intercalation, protective layers of Zn anode, hosts for Zn deposition, substrates, and separators. Finally, perspectives are put forward on further optimizing MXenes to improve the ZIS performance.

“…5,12−15 It is crucial to develop advanced cathode materials for the practical application of AZIBs. At present, manganese-based materials, 16−19 vanadium-based materials, 20−24 Prussian blue analogues 25−27 and phosphate materials 28,29 have been fabricated as cathode materials of AZIBs. Considering the limited operating voltage range, in order to obtain a high energy density, vanadium pentoxide (V 2 O 5 ) is a promising candidate due to its high theoretical zinc-storage capacity of 589 mA h g −1 based on the two-electron redox center (vanadium).…”

Aqueous zinc-ion batteries (AZIBs) are considered as an attractive alternative to lithium-ion batteries. Although the vanadium pentoxide (V 2 O 5 ) cathode exhibits high theoretical capacity of 589 mA h g −1 for zinc-storage, it suffers from capacity decay and sluggish Zn 2+ diffusion kinetics due to the strong electrostatic interactions with Zn 2+ , slight dissolution in aqueous electrolytes, and low electronic conductivity. Herein, the polyaniline and alkali-earth cation (Mg 2+ , Ca 2+ ) cointercalated V 2 O 5 composites (PVO-Mg, PVO-Ca) are fabricated to boost the zinc ion storage performance of vanadium oxide cathodes. PVO-Mg exhibits an enlarged interlayer distance of 14.15 Å and a tremelliform nanoarchitecture composed of nanosheets. The intercalated polyaniline and alkali-earth cations not only expand the Zn 2+ diffusion channels but also form a pillar net which can improve the structural stability and electronic conductivity of the layered structure, contributing to superior electrochemical kinetics, interfacial kinetics, and Zn 2+ diffusion kinetics. Moreover, ex situ X-ray diffraction results of PVO-Mg show a nearly constant interlayer distance during the insertion and extraction of Zn 2+ , which indicates that polyaniline and Mg 2+ firmly support the layered framework and prevent the expansion and contraction of the interlayer distance. Ex situ X-ray photoelectron spectroscopy results of PVO-Mg reveal the highly reversible formations of Zn x (CF 3 SO 3 ) y (OH) 2x−y •nH 2 O on the electrode surface and Zn 2+ inserted PVO-Mg inside the electrode, as well as a H + and Zn 2+ insertion/extraction process during which the polyaniline serves as a H + reservoir and a capacity contributor. Consequently, the PVO-Mg electrode exhibits high capacity (387.0 mA h g −1 at 0.5 A g −1 ), ultrafast rate capability (199.3 mA h g −1 at 30 A g −1 ), improved cycling stability, and high reversibility and would be a promising cathode for high performance AZIBs.

An aqueous zinc–sulfur battery (AZSB) represents a promising next-generation energy storage technology as a result of its salient features of safety, affordability, and environmental benignity. The incorporation of earth-abundant and environmentally friendly sulfur cathodes, zinc anodes, and aqueous electrolytes, coupled with the high theoretical energy density, positions an AZSB as a cost-effective and scalable technology with potential applications in grid-scale energy storage and portable electronics. This review provides a comprehensive review of the current status of research in AZSBs, discussing challenges faced, recent advances, and future perspectives. The major challenges associated with the aqueous electrolyte, zinc anode, and sulfur cathode are discussed in detail with a rational classification. These challenges limit the performance, cycling stability, and overall efficiency of AZSBs. Various strategies to address these issues, including electrolyte modification and electrode design, are critically analyzed and evaluated. Specifically, the review highlights recent advancements in research, including the development of advanced electrolytes by adding additives and the synthesis of novel electrode materials for enhanced electrochemical performance. Further, the utility of advanced characterization techniques for understanding and predicting the reaction mechanism occurring in an AZSB is reviewed. Along with a review of ongoing research activities in the field, future prospects and potential applications of this novel battery technology are also explored. Overall, this review identifies the need for continued research and development efforts to overcome the remaining challenges and, thus, realize the full potential of AZSBs in practical energy storage applications.
