Abstract Structural engineering and creating atomic disorder in electrodes are promising strategies for highly efficient and rapid charge storage in advanced batteries. Herein, a nanohybrid architecture is presented with amorphous vanadium oxide conformally coated on layered V C MXene (a-VO /V C) via tunable anodic oxidation, which exhibits a high reversible capacity of 307 mAh g at 50 mA g , decent rate capability with capacity up to 96 mAh g at 2000 mA g , and good cycling stability as a cathode for sodium-ion batteries. The a-VO layer enables reversible and fast Na insertion/extraction...
