“…One is the cable‐type configuration, which is widely demonstrated in flexible Li‐ion cells and Li–air batteries ( Figure 13 a) 267. The cable‐type Zn–air battery usually has the structure of polymer electrolyte around the surface of central zinc belt, while the outside of polymer electrolyte is coated with flexible air electrode or directly with electrocatalysts.…”

Zn–air batteries are becoming the promising power sources for portable and wearable electronic devices and hybrid/electric vehicles because of their high specific energy density and the low cost for next‐generation green and sustainable energy technologies. An air electrode integrated with an oxygen electrocatalyst is the most important component and inevitably determines the performance and cost of a Zn–air battery. This article presents exciting advances and challenges related to air electrodes and their relatives. After a brief introduction of the Zn–air battery, the architectures and oxygen electrocatalysts of air electrodes and relevant electrolytes are highlighted in primary and rechargeable types with different configurations, respectively. Moreover, the individual components and major issues of flexible Zn–air batteries are also highlighted, along with the strategies to enhance the battery performance. Finally, a perspective for design, preparation, and assembly of air electrodes is proposed for the future innovations of Zn–air batteries with high performance.

“…After coating a layer of gel electrolyte comprising PVA and H 2 SO 4 , two composite yarns were twisted together and even co-woven with a conventional cotton yarn to form an electronic fabric. [48] Peng et al applied this fiber-shape design concept to various energy storage devices, including LIBs, [137,138] SCs, [138,139] lithium-air batteries (Figure 13a), [140] lithium-sulfur batteries, [141] aluminaair batteries, [142] and smart energy harvest devices, [143] as well as to integrated photoelectric conversion and energy storage wires. [144] Two parallel-aligned MWCNTs/ LiMn 2 O 4 cathode and MWCNTs/Li 4 Ti 5 O 12 anode were assembled into a wire-shaped LIB, [145] and the capacity declines by only around 3% after bending for 1000 cycles.…”

degree of the entire electronic systems. In the integrated flexible electronic system, energy storage devices [14,[16][17][18][19][20] play important roles in connecting the preceding energy harvesting devices and the following energy utilization devices (Figure 1). Rechargeable secondary batteries and supercapacitors (SCs) are two typical energy storage devices. [21] Several excellent review papers [21][22][23][24][25][26] reported significant progresses achieved in flexible lithium-ion batteries (LIBs) and SCs by taking advantage of novel electrode materials, current collectors, and solid-state electrolytes. The application areas and lifetime of flexible power sources strongly depend on their mechanical deformation tolerance and the electrical property retention under deformation. Qualified flexible power sources should be able to endure high strain induced by external mechanical deformation, such as bending, compressing, stretching, folding, and twisting, while maintaining their electrochemical performance stability and structural integrity. Therefore, the mechanical reliability assessment and electrical property analysis of flexible devices need to be given much attention for future application.Tolerance in bending into a certain curvature is the major mechanical deformation characteristic of flexible energy storage devices. Thus far, several bending characterization parameters and various mechanical methods have been proposed to evaluate the quality and failure modes of the said devices by investigating their bending deformation status and received strain. Some of these mechanical metrologies were derived from the early research on flexible semiconductor devices of micro-electromechanical system (MEMS) [27,28] and TFTs. [29] However, comparing those numerous measurement data with one another is difficult because of the various theories and methods adopted by different research groups and the lack of unified assessment criteria. [26] The flexibility of flexible devices is generally realized not only by use of intuitive soft electrode materials but also by optimizing their mechanical structural design. [25] Detailed analysis on bending mechanics combining experimental and theoretical results provide not only reliable test methods to describe the bending state but also guidance for configuration design of devices against mechanical failure.The current review emphasizes on three main points: (1) key parameters that characterize the bending level of flexible energy storage devices, such as bending radius, bending Flexible energy storage devices with excellent mechanical deformation performance are highly required to improve the integration degree of flexible electronics. Unlike those of traditional power sources, the mechanical reliability of flexible energy storage devices, including electrical performance retention and deformation endurance, has received much attention. To provide the guideline for the construction design of devices, the strain distribution and failure modes in the entire architecture should b...

“…Flexible electronics, electronics that can function under mechanical deformation, is in high demand toward a wide variety of new applications, including wearable electronics, flexible displays, electronic skins, energy storage, medical implants, sensors, and biological actuators 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12. To realize the function of these electronic devices, highly conductive electrodes, contacts, and interconnects with large mechanical flexibility (e.g., bending, folding, stretching, compressing, and twisting) are considered as one of the most important components.…”

A low‐cost, solution‐processed, versatile, microfluidic approach is developed for patterning structures of highly conductive metals (e.g., copper, silver, and nickel) on chemically modified flexible polyethylene terephthalate thin films by in situ polymer‐assisted electroless metal deposition. This method has significantly lowered the consumption of catalyst as well as the metal plating solution.
