Manganese dioxide was the first positive electrode material investigated as a host for Zn 2+ insertion in the rechargeable zinc-ion battery (ZIB) with a zinc metal negative electrode [ 1, 2, 3 ]. The electrolyte in ZIBs is typically an aqueous solution of zinc sulfate or trifluoromethanesulfonate (triflate).
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.
So far, the main electrolytes used in aqueous zinc-ion batteries are aqueous ZnSO 4 and zinc salts such as Zn (CF 3 SO 3) 2.
For example, Hu et al. reported a plasma-treated β-MnO 2 @C cathode material for aqueous Zn/MnO 2 batteries, as shown in Figure 10 C,D.
Energy storage mechanism of manganese-based zinc ion battery In a typical manganese-based AZIB, a zinc plate is used as the anode, manganese-based compound as the cathode, and mild acidic or neutral aqueous solutions containing Zn 2+ and Mn 2+ as the electrolyte.
