“…The MnO 2 nanoflake retains its flake‐like structure. However, the Bi 2 O 3 cannot maintain its dense flake structure but become nanoparticles, which leads to the drop of capacitance and is a common result for Bi 2 O 3 . The flexibility of the full cell has been further demonstrated, as shown in Figure f, and three of the flexible cells connected in series are able to light a LED for over 20 s.…”

Direct assembling of active materials on carbon cloth (CC) is a promising way to achieve flexible electrodes for energy storage. However, the overall surface area and electrical conductivity of such electrodes are usually limited. Herein, 2D metal-organic framework derived nanocarbon nanowall (MOFC) arrays are successfully developed on carbon cloth by a facile solution + carbonization process. Upon growth of the MOFC arrays, the sites for growth of the active materials are greatly increased, and the equivalent series resistance is decreased, which contribute to the enhancement of the bare CC substrate. After decorating ultrathin flakes of MnO and Bi O on the flexible CC/MOFC substrate, the hierarchical electrode materials show an abrupt improvement of areal capacitances by around 50% and 100%, respectively, compared to those of the active materials on pristine carbon cloth. A flexible supercapacitor can be further assembled using two hierarchical electrodes, which demonstrates an energy density of 124.8 µWh cm at the power density of 2.55 mW cm .

“…[1][2][3][4][5][6][7][8] As one of the most promising energy storage devices, aqueous zinc-ion batteries (ZIBs) has gained ever-increasing attention on account of its outstanding safety, high theoretical capacity (Zn: ≈820 mAh g −1 ), low cost as well as environmental benignity. [16][17][18] Despite these advanced features, one of the biggest block for ZIBs developed to date is their relatively low capacity in terms of the substantially inferior capacity of cathode materials than Zn anode.

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.

“…Aqueous rechargeable MBs have higher ionic conductivity and provide better rate performance than those using organic electrolytes . Nickel–bismuth (Ni//Bi) MBs, as an important kind of aqueous rechargeable MBs, play significant roles in MESDs because of their high operation stability, wide working potential, high capacity, and environmental friendliness .

On‐chip microbatteries (MBs) with excellent electrochemical performance have attracted great attention for applications in miniaturized electronics. However, the lack of strategy for well‐suited integration of microelectrodes with decent mechanical properties and high electrochemical performance in microdevices restricts the development of on‐chip MBs. This work proposes a promising planar nickel–bismuth (Ni//Bi) MB, constructed through the microelectromechanical system‐based fabrication process and facile electrodeposition of Bi anode and Ni1−xCox(OH)2 cathode. Benefiting from the large surface area and effective integration of electrodes, the fabricated Ni//Bi MB achieves a relatively high energy density of 12.3 μWh cm−2 and high stability with 84.44% capacity retention after 1000 cycles. With an attractive fabrication technique and outstanding electrochemical performance, the Ni//Bi MB shows great potential for prospective applications in portable devices/systems.
