Fluorinated carbon (CF x ) is one of the most promising cathode materials for metal primary batteries. However, usage CF zinc‐based batteries relatively seldom reported. Herein, employed as material Zn‐based batteries, and corresponding electrochemical performance under a series aqueous electrolytes also systematically investigated. The results reveal that among all investigated exhibits highest capacity with value high 827 mAh g −1 alkaline NaOH electrolyte environment, maximum can reach 632, 607, 352, 66 those weak (sodium potassium salts) acid (zinc environment. In addition to capacity, displays best rate remarkable power density 37607.19 W kg at current 50 000 mA largest specific energy 674 Wh 100 electrolytes. This work offers insights guidance design high‐performance Zn/CF which are characterized by their low cost, excellent safety performance, high‐power density.
