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.
Aqueous zinc-ion batteries (AZIBs) have emerged as a practically attractive option for electrical storage because of environmentally benign aqueous-based electrolytes, high theoretical capacity of Zn anode, and significant global reserves of Zn. However, application of AZIBs at the grid-scale is restricted by drawbacks in cathode material (s).
The energy storage mechanisms and optimization strategies of Mn-based materials for aqueous zinc batteries are summarized. The relationship between electrochemical performance, reaction mechanism, and inherent crystal structures is revealed. The challenges and perspectives of Mn-based materials for aqueous zinc batteries are discussed.
