The hydrogen-bond network structure and solvation structure of the electrolyte are reconstructed by glycerol (GL) and methylsulfonamide (MSA) to achieve low-temperature durability in aqueous zinc-ion batteries (AZIBs). GL and MSA collaboratively construct (100)-oriented high-activity dendrite-free zinc anode to improve the rate performance of AZIBs. The Zn||Zn symmetrical cell achieved stable operation for 4,000 h at 1 mA cm−2 and 1 mAh cm−2 (30 °C) and 5,400 h at 0.5 mA cm−2 and 0.5 mAh cm−2 (−20 °C).

Aqueous zinc-ion batteries (AZIBs) hold great promise for next-generation energy storage but face challenges such as Zn dendrite growth, side reactions, and limited performance at low temperatures. Here, we propose an electrolyte design strategy that reconstructs the hydrogen-bond network through the synergistic effect of glycerol (GL) and methylsulfonamide (MSA), enabling the formation of a (100)-oriented Zn anode. This design significantly broadens the operating current and tem...
