The advancement of flexible rechargeable Zn–MnO2 batteries largely relies on directional design and fabrication of flexible cathode materials. However, the sluggish electron transfer and inferior mass diffusion rate of MnO2 cathodes hinder their application in high‐power systems. Herein, the design of flexible 3D carbon nanotube (CNT) conductive networks as excellent electron and charge transfer substrates is reported to achieve a high‐rate MnO2 cathode. With further structural protection of conductive poly(3,4‐ethylenedioxythiophene) (PEDOT), Zn2+ storage kinetics in the composite CNT/MnO2/PEDOT (denoted as CMOP) the cathode is optimized to deliver high capacity of 306.1 mAh g−1 at 1.1 A g−1 and superior rate capability of 176.8 mAh g−1 when the current density increases by tenfold (10.8 A g−1), representing a state‐of‐the‐art of current MnO2 based cathodes. Moreover, the as‐assembled quasi‐solid‐state Zn–CMOP batteries with good mechanical properties can afford a high energy density of 379.4 Wh kg−1 (17.5 mWh cm−3) and a peak power density of 17.1 kW kg−1 (0.8 W cm−3). This innovative achievement will be a critical step forward toward next‐generation quick charging electronics.

Li‐ion batteries (LIBs) with excellent cycling stability and high‐energy densities have already occupied the commercial rechargeable battery market. Unfortunately, the high cost and intrinsic insecurity induced by organic electrolyte severely hinder their applications in large‐scale energy storage. In contrast, aqueous Zn‐ion batteries (ZIBs) are being developed as an ideal candidate because of their cheapness and high security. Benefiting from high operating voltage and acceptable specific capacity, recently, manganese‐based oxides with different various crystal structures have been extensively studied as cathode materials for aqueous ZIBs. This review presents research progress of manganese‐based cathodes in aqueous ZIBs, including various manganese‐based oxides and their zinc storage mechanisms. In addition, we also discuss some optimization strategies that aim at improving the electrochemical performance of manganese‐based cathodes, and the design of flexible aqueous ZIBs based on manganese‐based cathodes (MZIBs). Finally, this review summarizes some valuable research directions, which will promote the further development of aqueous MZIBs.

Rechargeable aqueous zinc-ion batteries (ZIBs) have attracted escalating attention recently, owing to their energy density, decreasing cost, advanced safety, and environmental benignity. Nevertheless, ZIBs still lack suitable cathode materials with stable cycling performance, owing to the high polarization of zinc ion. Therefore, developing candidate materials with excellent properties remains a great challenge. Herein, we successfully synthesize a novel Mn 3 O 4 @N-doped carbon matrix composite nanorods (Mn 3 O 4 @NC Nrs) by using MnOOH nano-rods (the self-sacrifice templates) and polypyrrole (carbon and nitrogen source). Benefiting from the N-doped carbon shell and the synergetic effect of Zn 2 + and Mn 2 + in the electrolyte, the Mn 3 O 4 @NC Nrs show superior cycling stability and long cycling features for ZIBs. Specifically, the zinc cell conducts a high reversible capacity of 280 mAh g À 1 at 100 mA g À 1 and retains a high reversible capacity of 97 mAh g À 1 at 1000 mA g À 1 after 700 cycles. In addition, the work provides a new approach to fabricate long-term and high-rate capability cathodes for ZIBs.[a] M.
