Abstract: Aqueous zinc-ion batteries (AZIBs) and, in particular, Zn//MnO 2 rechargeable batteries have attracted great attention due to the abundant natural resources of zinc and manganese, low cost, environmental friendliness, and high operating voltage. Among the various ways to improve the electrochemical performance of MnO 2 -based cathodes, the development of MnO 2 cathodes doped with metal ions or composites of MnO 2 with conducting polymers has shown such advantages as increasing the specific capacity and cycling stability. This mini-review focuses on the strategies to improve the electrochemical performance of manganese-based cathodes of AZIBs.
