However, the electrochemical mechanism at the cathode of aqueous zinc–manganese batteries (AZMBs) is complicated due to different electrode materials, electrolytes and working conditions. These complicated mechanisms severely limit the research progress of AZMBs system and the design of cells with better performance.
Herein, the electrochemical performance and the energy storage mechanism of different forms of manganese oxides as the cathode materials for aqueous zinc batteries and the issues of the zinc anode, the aqueous electrolyte and the separator are elaborated.
This review focuses on the electrochemical performance of manganese oxides with different crystal polymorphs in the secondary aqueous zinc ion batteries and their corresponding mechanism, the recent investigation of the zinc anode, the aqueous electrolyte, and the effect of the separator, respectively.
In recent years, efforts on optimizing the structure of the electrode, the separator, the electrolyte, and modifying the feature of the interface have been made by researchers to improve the electrochemical performance of the aqueous battery with zinc as the anode.
Zhang et al. reported a two-stage process of the aqueous zinc ion battery using β -MnO 2 as the cathode material. Firstly, the tunnel β -MnO 2 was transformed into the layered Zn-buserit. Then Zn 2+ ions reversibly intercalated/de-intercalated in/out of the layered Zn-buserit ( Fig. 2 (b) ).
The development of zinc–manganese batteries was first started with primary alkaline batteries in the 1860s, followed by secondary alkaline batteries. Later, the development of mild neutral and weak acid batteries made a breakthrough on the AZMBs with the superiority of safety, environmental benefits and long circular life.
