- Abstract
Zn-Mn aqueous batteries (ZMABs) have the potential for grid-scale energy storage due to their low cost, high safety, and eco-friendliness. Recent advancements in high-capacity cathodes, dendrite-free anodes, and functionalized electrolytes have brought rechargeable ZMABs closer to practical applications. However, challenges remain in stabilizing the interface, particularly in electrolyte regulation. A recent study published in the National Science Review reports on the development of a lean-water quasi-eutectic electrolyte that improves the reversible interfacial deposition and reaction kinetics of Mn-based cathodes in a long cycle process. The study highlights the importance of electrolyte optimization in addressing the energy density and lifespan limitations of ZMABs. pH balance, solvation regulation, and redox mediation are identified as effective strategies for durable ZMABs. The authors propose future research directions, including the design of novel pH buffer electrolytes, regulation of Mn2+ solvation structure, development of stable redox mediators, and the creation of wide-temperature electrolytes for improved performance.
