Abstract Global climate change necessitates urgent carbon neutrality. Energy storage is crucial in this effort, but adoption hindered by current battery technologies due to low energy density, slow charging, and safety issues. A novel liquid metal flow using a gallium, indium, zinc alloy (Ga 80 In 10 Zn , wt.%) introduced an alkaline electrolyte with air electrode. This system offers ultrafast charging comparable gasoline refueling (<5 min) as demonstrated the repeated long‐term discharging (123 h) process of 317 mAh capacity at density mA cm −2 average voltage 1.1 V. high practical 635.1 g −1 achieved brand‐new potential theoretical value 1004.4 . Microscopic numerical simulations reveal significant hydrogen evolution reaction dendrite suppression compared pure Ga electrodes. The potassium iodide (KI)‐modified ‐air exhibits reduced 1.77 V efficiency 57% over 800 cycles, outperforming conventional Pt/C Ir/C‐based systems 22% improvement. innovative addresses limitations traditional lithium‐ion batteries, Zn‐air contributing advanced global
