Zinc-ion batteries have demonstrated promising potential for future energy storage, whereas drawbacks, including dendrite growth, hydrogen evolution reaction, and localized deposition, heavily hinder their development practical applications. Herein, unlike elaborated structural design electrolyte excogitation, we introduce an effective parts-per-million (ppm)-scale additive, phosphonoglycolic acid (PPGA), to overcome the intrinsic issues of zinc negative electrode in mild acidic aqueous electrolytes. Profiting from absorbed PPGA on surface its beneficial interaction with bonds adjacent water molecules, stable symmetric stripping/plating ZnSO4 at around 25 oC was achieved, procuring 362 350 days operation 1 mA cm-2, mAh cm-2 10 respectively.
