The demand for energy storage is growing, and the disadvantages of lithium‐ion batteries are being explored to overcome them. Accordingly, aqueous zinc‐ion batteries (ZIBs) are developing very rapidly, owing to their high safety, environmental friendliness, high abundance of resources, and high cost performance. Over the last decade, ZIBs have made remarkable progress through extensive efforts in the field of electrode materials and through fundamental understanding of non‐electrode components, such as solid‐electrolyte interphase, electrolytes, separators, binders, and current collectors. In particular, the breakthrough in using separators on non‐electrode elements should not be overlooked as such separators have proven key to conferring ZIBs with high energy and power density. In this Review, recent progress in the development of separators in ZIBs is comprehensively summarized based on their functions and roles in ZIBs, including the modification of conventional separators and the development of novel separators. Finally, the prospects and future challenges of separators are also discussed to facilitate ZIBs development.

Aqueous zinc‐ion batteries (AZIBs) stand out among many monovalent/multivalent metal‐ion batteries as promising new energy storage devices because of their good safety, low cost, and environmental friendliness. Nevertheless, there are still many great challenges to exploring new‐type cathode materials that are suitable for Zn2+ intercalation. Vanadium‐based compounds with various structures, large layer spacing, and different oxidation states are considered suitable cathode candidates for AZIBs. Herein, the research advances in vanadium‐based compounds in recent years are systematically reviewed. The preparation methods, crystal structures, electrochemical performances, and energy storage mechanisms of vanadium‐based compounds (e.g., vanadium phosphates, vanadium oxides, vanadates, vanadium sulfides, and vanadium nitrides) are mainly introduced. Finally, the limitations and development prospects of vanadium‐based compounds are pointed out. Vanadium‐based compounds as cathode materials for AZIBs are hoped to flourish in the coming years and attract more and more researchers' attention.

The advent of the information age has promoted the development of smart wearable electronics for acquiring real-time data, such as smart bracelets, real-time health monitors, electronic skins, and smart clothes, [1][2][3][4][5][6][7][8][9] which has in turn promoted the development of power supply systems with high operational safety, long cycle life, high energy, and excellent deformability. Among recently developed flexible power supplies, [10][11][12][13][14] flexible lithium-ion (Li-ion) batteries have been dominantly employed in wearable electronics because of competitive chargedischarge efficiency (≈90%), high energy density (≈400 W h kg −1 ), durable cycling life (≈5000 cycles) and mature Li-ion battery infrastructure. [15] Moreover, wearable fiber Li-ion batteries can be woven into textiles, offering a convenient way to power wearable electronics. [16][17][18] Nonetheless, the safety and environmental risks caused by the usage of flammable/ toxic organic electrolytes restrict the further advance of Li-ion batteries and make them unsatisfied to be integrated with wearable electronic devices in proximity to the human body. [15,19] Further efforts are highly demanded to explore alternative power systems with promising energy density, reliable discharge-charge characteristics, long operation life, and good safety.In recent years, metal-air batteries have received widespread attention because of their remarkable theoretical energy density, environmental-friendliness, low fuel cost, and superior safety. [20][21][22][23] In particular, their unique half-open systems can continuously utilize the oxygen from ambient air instead of storing gaseous oxygen in closed systems, thus the required mass and volume of the air electrode can be largely minimized, resulting in high theoretical energy densities. [24] Compared to the theoretical energy density of Li-ion batteries with a closed system (460 Wh kg −1 ), lithium-air (Li-air) batteries exhibit much higher theoretical energy density (≈3500 W h kg −1 , based on the discharge product of Li 2 O 2 ). [25,26] Flexible wearable metal-air batteries, combining the flexible deformation feature and the high theoretical energy density, have become attractive energy supply systems for wearable electronic devices. Since 2015, wearable metal-air batteries (i.e., zinc-air (Zn-air), Li-air, aluminum-air (Al-air), sodium-air (Na-air), potassium-air (K-air), With the increasing popularity of personal wearable electronic devices used for healthcare, entertainment, and sports applications, the corresponding energy supply and space adaptability of devices are required to meet higher standards. Owing to large energy densities and intrinsic safety, wearable aqueous metal-air batteries have shown great potential to be energy storage/ conversion integrated systems for wearable electronic devices characterized by long-term low-power operation. In contrast to non-aqueous electrolytes, aqueous-based electrolytes exhibit greater ionic conductivity, higher operational safety, lower cost, and super...
