“…Significantly, as shown in Scheme S1, Supporting Information, H 2 O 2 has been researched to be used as a fuel in direct H 2 O 2 fuel cells, and it can be converted into electricity without a membrane from the self-oxidation and reduction reactions at the surface of the anode and cathode. [6,9] Inspired by the work mentioned earlier, we designed and fabricated a flexible wire-shaped fuel cell based on a biscrolled CNT yarn-based cathode and anode (Figure 1a-c). For the anode, the dispersion of nickel particles is drop-coated uniformly on stacked carbon nanotube sheets and twisted into a yarn with the assistance of ethanol.…”

Flexible fuel cells show great prospects as a power source in wearable devices due to their high efficiency and good reliability. Herein, a wire‐shaped fuel cell is designed by achieving two main breakthroughs; one is the fabrication of the catalyst‐loaded current collector for wire‐shaped electrodes, and the other is the membrane‐free configuration design according to a new fuel reaction mechanism. Successfully, a flexible wire‐shaped membraneless fuel cell (WFC) is fabricated for the first time by integrating a biscrolled carbon nanotube (CNT)@ Fe3[Co (CN)6]2 cathode and CNT@ nickel particles anode into a silicone tube with a liquid H2O2 fuel electrolyte. The resulting flexible WFC shows an open‐circuit potential (OCP) of 0.88 V and a power density of 6.28 mW cm−2. Moreover, it can retain the structural integrity and stability under repeated bending deformation. Hopefully, this article will pave the way for the next‐generation reliable wearable electronics.

Mg batteries utilizing divalent Mg2+ as charge carriers have been attracting significant attention for energy storage owing to their uniqueness in terms of low cost, high safety, and high energy density. However, the short cycling life arising from the accumulation of a passivation layer on the Mg anode prohibits their further development. Here, a new strategy to suppress the accumulation of the passivation layer is presented, thus stabilizing the Mg anode by constructing a robust interfacial layer using organic solvent‐in‐water electrolytes. The organic solvents decompose on the Mg anode to form a MgO, polyether Mg enriched organic‐inorganic hybrid interfacial layer, preventing free water attack to the Mg anode. In addition, the organic solvent forms an H‐bond with H2O to suppress the water activity and therefore protecting the Mg anode. As an illustration to benefits of the solvent‐in‐water electrolytes, a Mg‐MnO2 battery that is coupled by a MnO2 cathode in Mn2+/MnO2 chemistry with the Mg anode is developed. The Mg‐MnO2 battery exhibits a well‐maintained discharge plateau at ≈2.5 V and a discharging capacity of ≈500 mAh g−1 over 1000 cycles. This result highlights the feasibility to stabilize the Mg anode by interface engineering through the solvent‐in‐water electrolyte design.
