“…Wang et al prepared a flexible composite film anode (ZCN) by vacuum filtration, which consisted of homogeneously mixed zinc microspheres, carbon nanotubes, and nanocellulose (Figure 2D). 69 Using the ZCN film anode, the full battery retained stable capacity retention under a bending state in 80 cycles. At the same time, the Zn||Zn symmetrical cells with the flexible ZCN film anode showed lower and more stable overpotential, indicating smooth zinc deposition.…”

“…A layer-by-layer vacuum filtration method was adopted to prepare integrated flexible MnO 2 -Zn batteries. 69 In this method, the precursor dispersions of a cellulose fiber separator and a MnO 2 /CNT cathode were sequentially and continuously filtered into films on the preprepared zinc microsphere/ CNT/nanofibrillated cellulose anode film (ZCN), followed by freeze drying and pressing as an integrated zinc ion battery. This compact structure produced much smaller impedance of the as-prepared integrated batteries than that of the segregated batteries assembled by sandwiching a cellulose fiber separator between a Ti-foilbased cathode and a Zn foil anode.…”

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.

Aqueous zinc batteries (AZBs) are promising energy storage devices owing to their high safety, low cost, and environmental friendliness. However, energy density improvement and lifespan prolongation of AZBs are impeded by the poor reversibility of Zn anodes. Instead of focusing on restraining the water activity that has been widely discussed, this work reports a unique strategy to eliminate the side reactions, which is the simultaneous regulation of cation and anion fluxes by microporous material. The as‐synthesized protective layer possesses an excellent sieving ability to repel sulfate infiltration by channel effect and via the electric field, and homogenizes Zn ion flux to achieve a dendrite‐free morphology, which is confirmed by the electrochemical and theoretical investigations. The protected anode exhibits a long lifespan (2400 h), deep Zn plating/stripping, and high current tolerance (100 mA cm−2). As a result, the full battery achieves a capacity retention of 76.4% after 7500 cycles, and in the anode‐free configuration, a high energy density of 192.8 Wh kg−1 is observed, which is more than 50 times that of a full battery with a Zn foil anode. By regulating the cations and anions simultaneously, the proposed strategy provides a low‐cost remedy to achieve the practical scale‐up of AZBs.
