“…More importantly, the C Mo values of the quasisolid state electrolyte are significantly lower than those of the aqueous electrolyte. Despite a visible drop of capacity, this quasisolid state battery still delivers impressive capacities of 2.65 mAh cm −2 and 241.3 mAh g −1 , which are considerably surpassing most of the recently developed ZIBs and other aqueous batteries (Figure 4e), [9,17,33,[44][45][46][47][48][49][50] such as Ni(OH) 2 //FeO x battery (0.227 mAh cm −2 and 126 mAh g −1 at 1.5 A g −1 ), [46] NiO//ZnO battery (0.26 mAh cm −2 and 197.9 mAh g −1 at 0.38 A g −1 ), [45] Zn// Co 3 O 4 battery (0.324 mAh cm −2 and 162 mAh g −1 at 1 A g −1 ), [9] Zn// ZnMn 2 O 4 battery (0.3 mAh cm −2 and 150 mAh g −1 at 0.05 A g −1 ), [17] Zn//β-MnO 2 battery (0.516 mAh cm −2 and 258 mAh g −1 at 0.2 A g −1 ), [47] Zn//ɑ-MnO 2 battery (1.425 mAh cm −2 and 285 mAh g −1 at 0.1 A g −1 ), [33] Na + battery (0.43 mAh cm −2 and 43 mAh g −1 at 0.1 A g −1 ), [49] and Ni//Bi@C battery (1.79 mAh cm −2 and 139 mAh g −1 at 0.31 A g −1 ).

“…Specifically, it is able to keep more than 70.4% of its original capacity after 400 cycles, dramatically higher than the aqueous one (27.1%) and comparable to the recently reported Zn ion batteries. [9,17,33,[45][46][47]49,50] while the corresponding calculated the C Mo values are shown in Figure 4c. In addition, the C Mo of aqueous and quasisolid state electrolytes after different charge/discharge cycles were also monitored when the MoO 3 cathodes were applied to fabricate devices.…”

Exploration of high‐performance cathode materials for rechargeable aqueous Zn ion batteries (ZIBs) is highly desirable. The potential of molybdenum trioxide (MoO 3 ) in other electrochemical energy storage devices has been revealed but held understudied in ZIBs. Herein, a demonstration of orthorhombic MoO 3 as an ultrahigh‐capacity cathode material in ZIBs is presented. The energy storage mechanism of the MoO 3 nanowires based on Zn 2+ intercalation/deintercalation and its electrochemical instability mechanism are particularly investigated and elucidated. The severe capacity decay of the MoO 3 nanowires during charging/discharging cycles arises from the dissolution and the structural collapse of MoO 3 in aqueous electrolyte. To this end, an effective strategy to stabilize MoO 3 nanowires by using a quasi‐solid‐state poly(vinyl alcohol)(PVA)/ZnCl 2 gel electrolyte to replace the aqueous electrolyte is developed. The capacity retention of the assembled ZIBs after 400 charge/discharge cycles at 6.0 A g −1 is significantly boosted, from 27.1% (in aqueous electrolyte) to 70.4% (in gel electrolyte). More remarkably, the stabilized quasi‐solid‐state ZIBs achieve an attracting areal capacity of 2.65 mAh cm −2 and a gravimetric capacity of 241.3 mAh g −1 at 0.4 A g −1 , outperforming most of recently reported ZIBs.

Wearable electronic devices that can be directly worn on the human body or combined with daily textiles have experienced a booming development with the rapid development of mobile electronics. These wearable electronic devices strongly demand indispensable, high performance power systems with small size, high flexibility, and adaptability to comfort frequent deformations during usage. Fabricating high-performance energy storage systems in a 1D shape like fiber is recognized as a promising strategy to address the above issues. These fiber-shaped power systems with diameters from tens to hundreds of micrometers can adapt to various deformations for stable operation in close contact with the human body. It is also possible to further weave such 1D energy storage devices into breathable textiles with matching electrochemical performances for the wearable electronics. Here, the key advancements related to fiber-shaped energy storage devices are reviewed, including the synthesis of materials, the design of structures, and the optimization of properties for the most explored energy storage devices, i.e., supercapacitors, aprotic lithium-based batteries, as well as novel aqueous battery systems. The remaining challenges are finally discussed to highlight the future direction of the development of fiber-shaped energy storage devices. www.advelectronicmat.de harvesting in the 1D format is then highlighted. The remaining challenges in fiber-shaped energy storage devices are finally discussed to provide insights for the future development.
