【 摘 要 】

tsAromatic aldehyde additives were introduced to modify the interfacial environment between Zn sheet and electrolyte through an absorption-competition mechanism, thus effectively inhibiting the dendrite/by-products growth.Zn–Zn and Zn–MnO2 cells with the additives achieved much better cycling stability (over 3000 h under 1 mA cm−2/1 mAh cm−2 and 800 h under 5 mA cm−2/5 mAh cm−2 for symmetric cells) than that of pure ZnSO4 electrolyte.
