The world's mounting demands for environmentally benign and efficient resource utilization have spurred investigations into intrinsically green and safe energy storage systems. As one of the most promising types of batteries, the Zn battery family, with a long research history in the human electrochemical power supply, has been revived and reevaluated in recent years. Although Zn anodes still lack mature and reliable solutions to support the satisfactory cyclability required for the current versatile applications, many new concepts with optimized Zn/Zn 2+ redox processes have inspired new hopes for rechargeable Zn batteries. In this review, we present a critical overview of the latest advances that could have a pivotal role in addressing the bottlenecks (e.g., nonuniform deposition, parasitic side reactions) encountered with Zn anodes, especially at the electrolyte-electrode interface. The focus is on research activities towards electrolyte modulation, artificial interphase engineering, and electrode structure design. Moreover, challenges and perspectives of rechargeable Zn batteries for further development in electrochemical energy storage applications are discussed. The reviewed surface/interface issues also provide lessons for the research of other multivalent battery chemistries with low-efficiency plating and stripping of the metal.

“…Tan et al [157] synthetized a freestanding GPE planar sheet, derived from a highly crosslinked homo-polymer, which enabled bendable metal-air batteries with high performance in the absence of any kind of mechanical supports. The crosslinked polymer, polyacrylamide (PAM), was synthesized via an ultraviolet (UV) light-initiated radical polymerization of acrylamide monomers using N,N -methylenebis-(acrylamide) (MBA) as the crosslinkers.…”

With the flourish of flexible and wearable electronics gadgets, the need for flexible power sources has become essential. The growth of this increasingly diverse range of devices boosted the necessity to develop materials for such flexible power sources such as secondary batteries, fuel cells, supercapacitors, sensors, dye-sensitized solar cells, etc. In that context, comprehensives studies on flexible conversion and energy storage devices have been released for other technologies such Li-ion standing out the importance of the research done lately in GPEs (gel polymer electrolytes) for energy conversion and storage. However, flexible zinc batteries have not received the attention they deserve within the flexible batteries field, which are destined to be one of the high rank players in the wearable devices future market. This review presents an extensive overview of the most notable or prominent gel polymeric materials, including biobased polymers, and zinc chemistries as well as its practical or functional implementation in flexible wearable devices. The ultimate aim is to highlight zinc-based batteries as power sources to fill a segment of the world flexible batteries future market.

“…[ 24,25 ] The new emerging flexible metal–air batteries are supposed to the ideal candidates for flexible electronics due to their high energy density. [ 26–35 ] Different from the metal‐ion batteries with the intercalation mechanism, the metal–air batteries operated through the oxygen reduction/evolution reaction (ORR/OER). [ 36–38 ] The metal–air battery holds a semiopen structure that the O 2 as the active material does not store in it, reducing the battery mass and volume and improving its energy density.…”

volume and improving its energy density. [39-47] Under the proposition of guaranteeing electrochemical performance, the components in the flexible metal-air battery, including active cathodes, metal anodes, separators, current collectors, and packaging materials, should be flexible to endure frequent mechanical strain. [48-54] Moreover, the safety of flexible battery is paramount during repeated deformation conditions. [55-60] Up to now, there are many flexible metal-air batteries have been proposed, such as flexible lithium (Li)-air battery, flexible Li-CO 2 battery, flexible zinc-air battery, flexible aluminum-air battery, silicon-oxygen battery, and so on. [61-71] Among various metalair batteries, Li-air batteries have raised much concern and got rapid development as a result of their theoretical energy density up to 5928 Wh kg −1 , eco-friendly, good reversibility, and high operating voltage of 2.96 V. [24,25,72-74] Here, we review the latest advances of flexible Li-air battery, focusing on the fabrication of flexible cathodes for improving the electrochemical performance, development of electrolyte for obtaining long durability, design of battery structure for achieving high flexibility. It should be noted that some reported studies on Li-air batteries were tested in the oxygen atmosphere rather than the ambient air, which is described as "Li-O 2 batteries." [27,75] 2. Flexible Cathodes The typical Li-air battery commonly made of Li metal anode, air cathode and aprotic electrolyte, which worked through the reaction of 2Li + O 2 → Li 2 O 2 (E OCV = 2.96 V). [76-80] As mentioned above, all components in flexible Li-air batteries should be flexible to accommodate stresses and strains in deformation. [10] However, the cathode and current collector are typically rigid carbon paper or porous metal, which hardly meet the needs of flexible Li-air battery, seriously restricting the development of the battery flexibility. [81-83] Moreover, the cathode should possess high catalytic activity to facilitate the OER and ORR reactions of Li-air battery, and porous structure to store the discharge products. [84-88] Therefore, it is urgently required to develop flexible and high-performance cathode materials with high mechanical stability for flexible Li-air batteries. Different from carbon paper with a rigid structure, carbon cloth is flexible that woven from multistrands of carbon fiber. Because of its mechanical flexibility and conductivity, carbon cloth was widely used as a flexible substrate material for the cathode in Li-air battery. [89-92] Liu et al. first proposed a flexible Li-O 2 battery with a flexible and recoverable cathode that constructed on the carbon cloth by depositing densely TiO 2 Along with the popularity of flexible electronic products, the requirements for flexible energy storage devices are also increasing, including high energy density, long-term stability, and high-grade safety. Among various flexible energy storage devices, flexible lithium-air batteries are expected to be one of the best candidate...
