Abstract Aqueous zinc ion batteries (AZIBs) are promising candidates for next-generation energy storage systems due to their low cost, high safety, and environmental friendliness. As the critical c...
Aqueous zinc ion batteries (AZIBs) stand out among many aqueous rechargeable batteries, owing to their unique advantages.
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.
In recent years, manganese dioxide (MnO 2)-based materials have been extensively explored as cathodes for Zn-ion batteries. Based on the research experiences of our group in the field of aqueous zinc ion batteries and combining with the latest literature of system, we systematically summarize the research progress of Zn−MnO 2 batteries.
Rechargeable aqueous zinc-based (Zn-based) batteries have recently garnered considerable attention due to their safety, sustainability, and cost-effectiveness [1, 2, 3, 4, 5, 6]. Aqueous Zn||MnO 2 batteries, in particular, have been extensively studied since the early 1860s .
Ideally, it should have a cost under $100/kWh, energy density over 250 Wh/L, lifetime over 500 cycles, and discharge times on the order of 1–10 h. Considering some of these factors, alkaline zinc–manganese oxide (Zn–MnO 2) batteries are a potentially attractive alternative to established grid-storage battery technologies.
