“…It is well-known that the MnO 2 electrode shows gradual capacity fading during long-term cycling due to structural destabilization related to the Jahn-Teller distortion and partial Mn 3+ dissolution [133]. To overcome this disadvantage of structural destabilization and to enhance the electronic transport in MnO 2 that facilitates the discharge/charge rate of the electrode, doping with various elements, i.e., Ag, Sn, V, Ni, Cu, Al, etc., has been proposed [10,134,135]. The use of selected doping elements allows the properties of α -MnO 2 to be tuned for practical applications.…”

“…Alfaruqi et al [135] used a simple redox reaction between Mn(CH 3 COO) 2 ·4H 2 O and KMnO 4 in aqueous solution added to a solution containing V 2 O 5 to obtain α -MnO 2 nanoparticles after annealing at 450 °C for 5 h. This material was used as electrode for zinc-ion batteries. V-doped γ -MnO 2 used as the cathode in primary lithium batteries was prepared by the redox reaction of KMnO 4 and MnCl 2 ·4H 2 O with V 2 O 5 as dopant reagent in a 3:1:0.15 molar ratio.…”

Manganese dioxides, inorganic materials which have been used in industry for more than a century, now find great renewal of interest for storage and conversion of energy applications. In this review article, we report the properties of MnO2 nanomaterials with different morphologies. Techniques used for the synthesis, structural, physical properties, and electrochemical performances of periodic and aperiodic frameworks are discussed. The effect of the morphology of nanosized MnO2 particles on their fundamental features is evidenced. Applications as electrodes in lithium batteries and supercapacitors are examined.

“…Subsequently, Liu et al confirmed that doping iron in MnO 2 , causing anisotropic changes in lattice parameters, could increase the discharged capacity for LIBs at high rates. Inspired by these, Kim et al prepared a V‐doped MnO 2 at ambient temperature as the cathode for ZIBs. Due to increased specific surface area and enhanced electronic conductivity induced by V doping, the cathode delivered high discharged capacities and superior cycling performance compared to the pure MnO 2 electrode.…”

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.

“…[11][12][13] Meanwhile, it is of great importance to reduce the environment pollution and the cost by using aqueous electrolyte, but the high polarization, the narrow voltage range of Zn 2 + and the water splitting in the aqueous battery system limit many cathode materials for the intercalation of Zn 2 + . [18,25] Their poor electrical conductivity and large volume variation, however, still existed around the cycling. [24] The Mn-based cathode materials among the above ones are considered the most promising Zn 2 + -insertion cathode material due to the low cost, abundant resources, hypotoxicity, and good compatibilities in the aqueous battery systems.…”

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.
