Why is the electrochemical mechanism at the cathode of aqueous zinc–manganese batteries complicated?

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.

Are alkaline zinc-manganese dioxide batteries rechargeable?

Nature Communications 8, Article number: 405 (2017) Cite this article Although alkaline zinc-manganese dioxide batteries have dominated the primary battery applications, it is challenging to make them rechargeable. Here we report a high-performance rechargeable zinc-manganese dioxide system with an aqueous mild-acidic zinc triflate electrolyte.
