“…Since manganese has a variety of valence states, it could form a series of manganese oxides, such as MnO 2 (Alfaruqi et al, 2016), Mn 3 O 4 (Zhu et al, 2018), etc. Due to their special structure, they could be used as cathode materials for AZIBs (Khamsanga et al, 2019;Palaniyandy et al, 2019).…”

“…At present, many researchers are devoted to improve the electronic conductivity of MnO 2 and the cycling stability of MnO 2 -based AZIBs (Wu et al, 2018;Tang et al, 2019). α-MnO 2 , which have stable 2 × 2 tunnel structure, has received considerable attention in recent years as a cathode material for AZIBs ( Figure 1C; Palaniyandy et al, 2019;. In 2009, α-MnO 2 was first applied as a cathode material for AZIBs, and specific capacity reached 210 mAh g −1 at 0.2 A g −1 (Xu et al, 2009).…”

In recent years, aqueous rechargeable zinc-ion batteries (AZIBs) have attracted more and more attention not only because they use earth-abundant metals but also due to their improved safety and high volumetric energy density. As one type of promising electrode material for AZIBs, manganese-based materials are receiving considerable attention owing to their high theoretical specific capacity, non-toxicity, and low cost. This mini review summarizes the recent advances on the application of manganesebased materials (manganese oxide, manganate, and their composites) in AZIBs. In addition, the methods to enhance their zinc-ion storage properties are summarized and discussed, such as morphology engineering, doping, as well as compositing with other materials. Ultimately, some personal prospects for future research of the manganese-based materials for AZIBs are also proposed.

“…In recent years, on account of their low self-discharge, less memory effect and high efficiency, the implementation of MIBs for energy storage has become very popular [ 6 , 7 ]. Of different types of MIBs, lithium-ion batteries (LIBs) are widely used for various applications due to their high energy density and long cycle life [ 8 , 9 ]. However, some important factors such as high cost and safety issues tarnish the large-scale application of LIBs [ 10 , 11 ].…”

Due to their cost effectiveness, high safety, and eco-friendliness, zinc-ion batteries (ZIBs) are receiving much attention nowadays. In the production of rechargeable ZIBs, the cathode plays an important role. Manganese oxide (MnO2) is considered the most promising and widely investigated intercalation cathode material. Nonetheless, MnO2 cathodes are subjected to challenging issues viz. limited capacity, low rate capability and poor cycling stability. It is seen that the MnO2 heterostructure can enable long-term cycling stability in different types of energy devices. Herein, a versatile chemical method for the preparation of MnO2 heterostructure on multi-walled carbon nanotubes (MNH-CNT) is reported. Besides, the synthesized MNH-CNT is composed of δ-MnO2 and γ-MnO2. A ZIB using the MNH-CNT cathode delivers a high initial discharge capacity of 236 mAh g−1 at 400 mA g−1, 108 mAh g−1 at 1600 mA g−1 and excellent cycling stability. A pseudocapacitive behavior investigation demonstrates fast zinc ion diffusion via a diffusion-controlled process with low capacitive contribution. Overall, the MNH-CNT cathode is seen to exhibit superior electrochemical performance. This work presents new opportunities for improving the discharge capacity and cycling stability of aqueous ZIBs.

Nano‐crystalline, flake‐like Mn oxide was electrodeposited onto carbon paper (CP) using a pulsed electrodeposition technique. The electrodeposited Mn oxide was identified as Mn3O4 through a combination of X‐ray photoelectron spectroscopy (XPS), X‐ray diffraction (XRD), and Raman spectroscopy. The Mn3O4 on CP was used as a cathode for Zn‐ion batteries (ZIBs) and showed excellent cyclability at a current density of 1 A g−1 with a capacity retention of 139 % after 200 cycles. Electron microscopy was used to characterize the microstructural changes of the cathode at various stages during discharge/charge cycling. This work in combination with the electrochemical results suggests a two‐step reaction mechanism involving both intercalation and conversion reactions. The results demonstrate that electrodeposition of the cathode material is a simple, quick, and potentially scalable electrode synthesis method for producing high performing Zn‐ion electrodes without the use of binders or other additives.
