Abstract
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 materials for AZIBs, manganese-based materials are receiving considerable attention owing to their high theoretical specific capacity, nontoxic and low cost. This minireview summarizes the recent advances on the application of manganese-based materials (manganese oxide, manganate, and their composites) in aqueous rechargeable zinc-ion batteries. 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.
