“…44,45 The FAMIBs with metal foil anodes were reported to have high capacity retention under different bending angles. Paired with a flexible cathode and a hydrogel electrolyte, a Zn foil was incorporated as a part of a flexible quasi solid-state V 2 O 5 -Zn battery by Liang et al 46 The as-prepared battery was tested under different mechanical conditions, such as hammering, weight loading, drilling, sewing, cutting, and bending (Figure 1A), which could retain a high capacity retention above 80% compared to its original state, indicating the excellent potentially practical use of metal foil anodes in reliable and tailorable FAMIBs. To further improve the mechanical property of Zn metal anodes, Liu et al prepared a Zn micromesh anode by photolithography and electrochemical machining techniques (Figure 1B).…”

Flexible aqueous batteries have been thriving with the growing demand for wearable and portable electrical devices. In particular, flexible aqueous multivalent ion batteries (FAMIBs), the charge carriers of which include Zn 2+ , Al 3+ , Mg 2+ , and Ca 2+ , have great potential for development owing to their high safety, high elemental abundance in the Earth's crust, and a multielectron redox mechanism with a high theoretical specific capacity. Therefore, for a comprehensive understanding of this developing field, it is necessary to summarize the recent research progress of FAMIBs in a timely manner.Herein, the advancements of the state-of-the-art FAMIBs are reviewed, and the prospects toward this field are also proposed. This study focuses on the rational material and configuration design for FAMIBs in recent studies to achieve high battery performances under deformation conditions, which is elaborated on by classification of the anode, cathode, hydrogel electrolyte, and configurations of FAMIBs. Besides, the electrochemical performance of FAMIBs under flexible conditions is also reviewed from the perspective of their working voltage, specific capacity, and cycling stability. Finally, the approaches to improve the performance of FAMIBs are comprehensively evaluated, followed by the outlook on the challenges and opportunities in future development of FAMIBs.

Flexible zinc–nickel batteries (FZNBs) have been considered as a promising power supply for wearable electronics due to the intrinsic safety, high operating voltage and superior rate performance. However, the serious self‐corrosion of zinc and the redistribution of dissolved [Zn(OH)4]2− on the electrode surface limit the electrochemical performance of FZNBs. Herein, the nanofluid electrolyte with fumed Al2O3 additive is introduced into FZNBs and a protective layer is formed due to the adsorption of Al2O3 on the electrodeposited zinc anode. The protective layer strengthens the zincophilicity of the anode and homogenizes the deposition of [Zn(OH)4]2−, avoiding the dendrite formation and the shape change of electrode. Meanwhile, by suppressing the [Zn(OH)4]2− diffusion from the anode surface to the bulk electrolyte, the interface stabilization is effectively promoted, thereby improving zinc utilization rate and inhibiting the corrosion. Hence, the FZNBs assembled with Al2O3‐nanofluid electrolyte and electrodeposited zinc anode demonstrates superior energy density of 210 Wh L−1 with a stable cycling of 575 h. Furthermore, FZNBs modified with Al2O3‐nanofluid electrolyte have a promising future in the field of wearable and portable electronics.
