Renewable energy technologies, such as solar cells and wind turbines, are becoming increasingly widespread in many countries worldwide. Reliably storing the electricity produced by these devices, so that it can be used later at times when sunlight or wind are scarce, would further improve their effectiveness as sustainable energy solutions.

A promising solution to store solar and wind energy entails the use of aqueous zinc (Zn) metal batteries. These are low-cost, safe and environmentally friendly batteries that store and release energy, leveraging water-based solutions and Zn anodes.

Despite their potential, Zn batteries have not yet achieved the de...
