Abstract Flexible rechargeable zinc‐ion batteries (ZIBs) have aroused tremendous attention owing to the good safety and abundant reserves, making it one of most promising alternatives for novel energy storage devices. Herein, flexible, free‐standing hybrid films with a three‐dimensional interlaced network are reported ZIBs. The flexible pliable VO 2 /MXene deliver high specific capacity 228.5 mAh g −1 at 0.2 A display reversible over 126.6 after 700 cycles . More impressively, electrode also shows exciting mechanical flexibility outstanding Zn 2+ capability moderate retention 72.1 % 2500 5 in quasi‐solid‐state special structure can boost diffusion pathway effectively stabilize upon cycling. This work evidences that own an immense potential portable equipment.
