Aqueous zinc ion batteries represent promising next-generation energy storage systems, but unwanted side reactions such as hydrogen evolution and zinc dendrite formation can significantly impact their Coulombic efficiency and lifespan. Here, dimethyl sulfoxide and nanodiamond additives are introduced to a ZnSO4 electrolyte, effectively inhibiting side reactions and dendrite formation through hydrogen bond fusion, and enabling exceptional cycling stability for over 1500 h at 1 mA cm−2.
