Electrolyte design for aqueous Zn batteries

Context & scaleZn-based batteries with aqueous electrolytes are garnering great interest as the most promising next-generation batteries due to their intrinsic high safety, low cost, and environmental friendliness. However, the short cycle life of the Zn battery, originating from the low reversibility of the Zn metal electrode, is far from satisfactory. To achieve high reversibility of Zn metal electrode, tackling the water decomposition reaction and the inhomogeneous deposition/dissolution reaction is crucial. We present design principles for aqueous co-solvent electrolytes with high Zn reversibility and suggest a new parameter for accurately selecting beneficial organic molecules for Zn-based batteries.…
