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.
We emphasize that the focus of our review is on alkaline Zn–MnO 2 batteries rather than Zn–MnO 2 batteries with near-neutral or mildly acidic electrolytes (“zinc-ion batteries”), which are already covered extensively in other recent reviews [, , , , , , ].
At the same time, through the in-depth understanding of the reaction process and failure mechanism, it is necessary to establish the connection between the laboratory scale and the actual application conditions, which is also the key for the industrialization of aqueous zinc–manganese batteries.
The electrochemical reaction mechanism of the alkaline Zn/MnO 2 battery can be described as the dissolution/deposition of Zn anode and conversion reactions related to H + at the cathode (Fig. 8 d) . The electrochemical equations of alkaline Zn/MnO 2 cell are as follows:
An alkaline battery uses zinc powder as the anode. This has the effect of Increasing the rate of reaction and hence electron flow. Making the battery last longer. Making the battery more durable. A battery left operating in a toy car for several weeks starts to break apart.
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.
