“…Given the looming concerns over the availability and safety hazards of lithium resources, rechargeable zinc-ion batteries (ZIBs) are relatively abundant in resources and environmental benign as compared to alkaline metals. To add in the easy manufacturing process, good safety characteristics and mature recycling process, ZIBs are the cost-effective solution for stationary applications in the long run as well [6][7][8][9]. Nevertheless, for most ZIBs, their specific capacity, cycling stability and rate capability are limited by cathode materials [10][11][12][13].…”

HIGHLIGHTS• 3D flower-like architecture assembled by NH 4 V 4 O 10 nanobelts (3D-NVO) was fabricated.• The Zn 2+ ion was intercalated into NVO cathode within the interlayer region (NH 4 V 4 O 10 ↔ Zn x NH 4 V 4 O 10 ).• The 3D-NVO cathode could deliver a large reversible capacity of 485 mAh g −1 at a current density of 100 mA g −1 for zinc-ion battery.ABSTRACT Given the advantages of being abundant in resources, environmental benign and highly safe, rechargeable zinc-ion batteries (ZIBs) enter the global spotlight for their potential utilization in large-scale energy storage. Despite their preliminary success, zinc-ion storage that is able to deliver capacity > 400 mAh g −1 remains a great challenge. Here, we demonstrate the viability of NH 4 V 4 O 10 (NVO) as high-capacity cathode that breaks through the bottleneck of ZIBs in limited capacity. The firstprinciples calculations reveal that layered NVO is a good host to provide fast Zn 2+ ions diffusion channel along its [010] direction in the interlayer space. On the other hand, to further enhance Zn 2+ ion intercalation kinetics and long-term cycling stability, a three-dimensional (3D) flower-like architecture that is self-assembled by NVO nanobelts (3D-NVO) is rationally designed and fabricated through a microwave-assisted hydrothermal c b NH 4 Zn 2+ Zn 2+ + 700 550 400 250 100 Discharge Charge Coulombic efficiency 0 1 0 2 0 Cycle number 30 40 50 Coulombic efficiency (%) 100 80 60 40 20 0 485 mAh g −1 Capacity (mAh g −1 )method. As a result, such 3D-NVO cathode possesses high capacity (485 mAh g −1 ) and superior long-term cycling performance (3000 times) at 10 A g −1 (~ 50 s to full discharge/charge). Additionally, based on the excellent 3D-NVO cathode, a quasi-solid-state ZIB with capacity of 378 mAh g −1 is developed.

“…In hydrogel‐based electrolyte, HER is inevitable, which takes place during Zn plating process due to the existence of aqueous solution. Subsequently, the concentration of OH − increases, leading to the side reactions accompanied with the formation of Zn(OH) 2 , zincates, and ZnO 199. These byproducts are aggravated by the interaction between Zn 2+ and H 2 O molecules.…”

Aqueous rechargeable zinc ion batteries (ZIBs) have been deemed to be possible candidates for large‐scale energy storage due to their ecoefficiency, substantial reserve, safety, and low cost. However, the challenges inherent in aqueous electrolytes, such as water splitting reactions, water evaporation, and liquid leakage, have greatly hindered their development in energy storage. Fortunately, polymer electrolytes would be able to overcome the abovementioned challenges. Moreover, the flexible properties of polymer electrolytes can facilitate their future application in wearable electronics. Recently, increasing attention has been attracted to the polymer electrolyte‐based zinc ion batteries. However, the development of polymer electrolytes for ZIBs is still in the early stages due to numerous challenges. Therefore, substantial research effort is required to overcome the challenges of polymer electrolyte‐based ZIBs. In this review, the current progress in developing polymer electrolytes, including solid polymer electrolytes, gel polymer electrolytes, and hybrid polymer electrolytes, as well as the interactions between electrodes and polymer electrolytes for ZIBs is comprehensively reviewed, analyzed, and discussed in terms of their synthesis, characterization, and performance validation. To facilitate further research and development of polymer electrolytes for ZIBs, the relevant challenges are summarized and analyzed, and some underlying approaches to overcome these challenges are also proposed.

With the increase of device requirements, rechargeable lithium‐ion batteries are facing tremendous challenges in large‐scale applications due to the high price and gradual shortage of lithium sources. In contrast, multivalent ion batteries, such as aluminum, magnesium, and zinc, are promising candidates for the next‐generation energy‐storage systems because of their high volumetric energy density, safe operation, and abundant reserves. The strong intercalation between multivalent ions and the host materials, however, will cause lower ion‐diffusion kinetics and a poor discharge capacity. One of the main challenges is to search for a suitable cathode material with a high capacity and good structural stability to overcome the abovementioned problems. Two‐dimensional layered materials, with characteristic unique structural features, good conductivity, and high electrochemically active surface, have attracted attention from researchers during the past decade. In this review, the design approach and synthetic procedures for the preparation of two‐dimensional materials as cathodes for multivalent ion batteries, including interlayer engineering, two‐dimensional heterostructures, pore/hole engineering, and heteroatom doping, are summarized. Meanwhile, the relationship between the design configuration and optimized electrochemical performance is rationally and systematically presented. Additionally, perspectives for the sustainable synthesis of cathode materials are proposed for multivalent metal‐ion chemistry.
