“…Therefore, developing flexible electrodes, especially flexible SIBs, to meet the ever-growing demands of flexible electronics is a most urgent task. Along with the avenues of research on flexible LIBs, [17][18][19][20][21] flexible SIBs have emerged as a rapidly growing and enormously promising field. In view of the rapidly booming attention on flexible SIBs, it is necessary to highlight the recent progress and perspectives.…”

“…In view of the rapidly booming attention on flexible SIBs, it is necessary to highlight the recent progress and perspectives. To the best of our knowledge, there have already been several excellent reviews devoted to SIBs [11][12][13][14][15][16] or flexible energy-storage devices, [17][18][19][20][21] but so far, there has been no comprehensive review focusing on flexible electrodes for SIBs up to now. Thus, the topic considered here is timely.…”

accessible lithium reserves are in remote or in politically sensitive areas. [5] This fact should sound the alarm for the expanded application of LIBs, because the increasing demand for LIBs could cause the price of lithium to skyrocket. It is even predicted that the world will run out of lithium supplies in the foreseeable future. [6][7][8] It is well known that sodium resources are more abundant (abundance: 23.6 × 10 3 mg kg −1 vs 20 mg kg −1 ) and vast (for example, the United States alone possesses 23 billion tons of soda ash which is a sodium-containing precursor) than lithium analog. Additionally, the trona (about $135-165 per ton), which could be used to produce sodium carbonate, has much lower cost than lithium carbonate (about $5000 per ton in 2010). [9,10] These two features endow SIBs with fascinating advantages for large-scale EES applications in the near future. Without doubt, SIBs also face big challenges: performance improvement and technological innovation. Although sodium has similar physical and chemical properties to lithium, the larger ionic radius of sodium ions compared with that of lithium ions restricts the insertion and extraction of sodium ions from the host materials commonly explored for LIBs. To address this problem, optimizing the chemical composition, tailoring the lattice structures, and regulating the morphologies of the host materials seem to be the most applicable strategies, and there have already been several excellent reviews. [11][12][13][14][15][16] As for technological innovation, the traditional fabrication processes mainly based on the slurrycasting method not only make SIBs typically rigid, thick, bulky, and heavy, but also reduce the overall volumetric/gravimetric energy density of the electrode. In the traditional slurry-casting method, the binders are insulating and electrochemically inactive, which can not only decrease the electrical conductivity, but also has a detrimental effect on the cycling stability resulting from some side effects between the electrolyte and inactive materials. In addition, the heavy weight of the binders, conductive additives and current collectors also reduces the volumetric/ gravimetric energy density of the overall electrode. Therefore, to enhance the battery performance and simplify the preparation process, the traditional slurry-casting method should be improved or even replaced; in other words, avoiding the use of binder, conductive additive, and metal current collector.In contrast, flexible electrodes are usually made from various active materials built on flexible conductive substrates without binder, conductive additive, and even metal current collector, Sodium-Ion Batteries

“…To date, there have been many review articles providing the excellent summaries of research trends for the LIBs. However, most previous published review articles have mainly focused on the structural deformability or novel designs of active materials or cells . Thus, the critical review of the flexible LIBs is urgently needed in terms of the practical application.…”

With the advent of flexible electronics, lithium-ion batteries have become a key component of high performance energy storage systems. Thus, considerable effort is made to keep up with the development of flexible lithium-ion batteries. To date, many researchers have studied newly designed batteries with flexibility, however, there are several significant challenges that need to be overcome, such as degradation of electrodes under external load, poor battery performance, and complicated cell preparation procedures. In addition, an in-depth understanding of the current challenges for flexible batteries is rarely addressed in a systematical and practical way. Herein, recent progress and current issues of flexible lithium-ion batteries in terms of battery materials and cell designs are reviewed. A critical overview of important issues and challenges for the practical application of flexible lithium-ion batteries is also provided. Finally, the strategies are discussed to overcome current limitations of the practical use of flexible lithium-based batteries, providing a direction for future research.

Double-Layer Membrane Cathode with Improved Oxygen Diffusivity in Zinc-Air Batteries AbstractThe commercialization of portable zinc-air batteries has been limited to the coin cell shape, mainly due to issues related to the cathode morphology. These types of batteries commonly use an aqueous electrolyte, which is susceptible to changes in air temperature and humidity that can cause leakage and block the air-cathode. This problem entails the use of bulky systems that require an empty gap between the porous cathode and the electrolyte to avoid flooding. This paper presents a novel fabrication method and morphology for a conductive and flexible doublemembrane nanocomposite air-cathode. The pore morphology for each membrane was designed for two purposes using two different foaming techniques. The foaming technique includes supercritical CO 2 in a high-pressure chamber to create a hydrophobic closed-cell structure. On the other hand, NaCl was used as a temporary space-holder to create a hydrophilic open-cell morphology. The closed-cell membrane presented an optimal performance as a hydrophobic oxygen diffusion layer whereas the hydrophilic open-cell membrane, apart from increasing the catalytic surface area, also increased the water absorption by 12 times with a swelling capacity of 68%. The electrochemical tests exhibited stable performance without presenting leaking even when bent under a relative humidity of 85-90 %. The specific energy density achieved was as high as 198 W h kg -1 , which is similar to that of some of the available commercial alkaline cells.Furthermore, the double-membrane air-cathode also has the advantages of low cost, high recyclability and the possibility of multiple configurations including flexibility for both primary and secondary configurations.
