Abstract Construction advanced fibers with high Faradic activity and conductivity are effective to realize energy density sufficient redox reactions for fiber‐based electrochemical supercapacitors (FESCs), yet it is generally at the sacrifice of kinetics structural stability. Here, a high‐entropy doping strategy proposed develop high‐energy‐density FESCs based on doped metal oxide@graphene fiber composite (HE‐MO@GF). Due synergistic participation multi‐metal elements via doping, HE‐MO@GF features abundant oxygen vacancies from introducing various low‐valence ions, lattice distortions, optimized electronic structure. Consequently, maintains active sites, low diffusion barrier, fast adsorption kinetics, improved conductivity, enhanced stability, Faradaic reversibility. Thereinto, presents ultra‐large areal capacitance (3673.74 mF cm −2 ) excellent rate performance (1446.78 30 mA in 6 M KOH electrolyte. The HE‐MO@GF‐based solid‐state also deliver (132.85 µWh ), good cycle (81.05% capacity retention after 10,000 cycles), robust tolerance sweat erosion multiple washing, which woven into textile power wearable devices (e.g., watch, badge luminous glasses).
