“…The solid-state DEFC delivers an energy density up to 13.63 mWh cm −2 , which is among the highest reported to date, outstripping most batteries such as Zn-ion batteries, [58] Li-ion batteries, [59][60][61] Ni-Fe batteries, [62] solid-state Zn-air batteries [63] and other alcohol fuel cells [1] (Figure 7e). Besides, the power density is as high as 12.71 mW cm −2 , which is superior to many high-performance fuel cells, for instance, biofuel cell, [64,65] urea fuel cells, [66,67] methanol fuel cells, [68,69] solid-oxide fuel cell [70] and some alcohol fuel cells [71] (Figure 7f).…”

As in many other electrochemical energy‐converting systems, the flexible direct ethanol fuel cells rely heavily on high‐performance catalysts with low noble metal contents and high tolerance to poisoning. In this work, a generic dealloying procedure to synthesize nanoporous multicomponent anodic and cathodic catalysts for the high‐performance ethanol fuel cells is reported. On the anode side, the nanoporous AlPdNiCuMo high‐entropy alloy exhibits an electrochemically active surface area of 88.53 m2 g−1Pd and a mass activity of 2.67 A mg−1Pd for the ethanol oxidation reaction. On the cathode side, the dealloyed spinel (AlMnCo)3O4 nanosheets with no noble metals demonstrate a comparable catalytic performance as the standard Pt/C for the oxygen reduction reaction, and tolerance to high concentrations of ethanol. Equipped with such anodic and cathodic catalysts, the flexible solid‐state ethanol fuel cell is able to deliver an ultra‐high energy density of 13.63 mWh cm−2 with only 3 mL ethanol, which is outstanding compared with other similar solid‐state energy devices. Moreover, the solid‐state ethanol fuel cell is highly flexible, durable and exhibits an inject‐and‐run function.

Humans live today in a high‐tech and informationalized society. With the development of the emerging electronic information age, various electronic systems are inclined to be multifunctional and miniaturized. It is urgent to develop “small and powerful” micro‐batteries with flexibility and high electrochemical performance to meet the diverse needs of microelectronic components. However, low electrochemical performance exists in traditional microenergy storage devices, which fail to satisfy the energy needs for microdevices. Here, for the first time, a planar integrated flexible rechargeable dual‐ion microbattery (DIMB) is reported, which is fabricated from an interdigital pattern of graphite as an electrode and lithium hexafluorophosphate as an electrolyte. As a microbattery, the DIMB exhibits a high reversible capacity of 56.50 mAh cm−3, and excellent cycle stability with 90% capacity retention after 300 cycles under a high working voltage. The application of DIMB in microdevices, such as light‐emitting diodes (LEDs), digital electronic game consoles, and electrochromic glasses is also investigated, fully demonstrating its “small and powerful” performance. The integrated DIMB is a high‐voltage microdevice that reaches a nonpareil discharge voltage of about 100 V and a charging capacity of 102 mAh g−1. This dual ion‐based flexible microbattery could become a promising candidate for energy storage and conversion components in next‐generation microelectronic devices and integrated electronic devices.

“…Thus, the hydrogel showed, after soaking, over 1000% stretchability, without any breakage or even visible cracking, together with a 0.28 Scm −1 . At this point, the last work moves us to summarize and clarify the relationship between PVA, PAM and PAA/PANa and their healing and energy-dissipative properties in dual network hydrogel already, or to be, mentioned in this review in several references [153,154,168,273,274]. To this aim, the work done by Gong et al [275] is taken as reference.…”

“…There are multiple combinations of polymers often used as host in the GPEs. A representative example of copolymerization was reported by Z. Cao et al [168], who designed and synthesized a poly(acrylamide-co-acrylic acid) alkaline GPE, named as P-(AM-co-AA), to be applied in a planar zinc-air battery. The aim of the authors was to improve the mechanical properties of the PAA-KOH polymer, which can retain a high amount of water but, great retention, makes a pure PAA gel weak and brittle because the formed hydrogen bonds are constantly challenged by surrounding water molecules.…”

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.
