Secondary aqueous zinc-ion batteries have been widely investigated recently due to their high energy density, low-cost, and environmental friendliness, compared to organic batteries.Zinc based batteries still have unstable cycle performance, especially at a low current density, which usually presents severe declination of the specific capacity during cycling.
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.
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 energy storage mechanism in zinc-ion batteries is mainly based on the intercalation and delamination of zinc ions between the lattices of vanadium-based oxides. During discharge, Zn 2+ are inserted into the cathode while Zn in the anode loses electrons to form Zn 2+, thus maintaining the charge balance of the electrolyte.
At present, several mechanisms have been proposed in zinc-manganese batteries: Zn 2+ insertion/extraction reaction, [ 17, 22, 23] chemical conversion reaction, H+ /Zn 2+ co-insertion/extraction reaction , , , dissolution-deposition mechanism , , , , etc.
Zinc-ion batteries (ZIBs) rely on a lithium-ion-like Zn 2+ -shuttle, which enables higher roundtrip efficiencies and better cycle life than zinc-air batteries. Manganese-oxide cathodes in near-neutral zinc sulfate electrolytes are the most prominent candidates for ZIBs.
Regardless of the reaction mechanism adopted by manganese-based batteries, electrochemically inactive by-products would be generated at the cathode after long-term cycling, which is a severe impediment to a long lifespan of the battery.
