• A novel in situ N and low‐valence‐state Mo dual doping strategy was employed to significantly improve the conductivity, active‐site accessibility, and electrochemical stability of MoO3, drastically boosting its electrochemical properties. Consequently, our optimized N‐MoO3−x nanowires exhibited exceptional performances as a bifunctional anode material for both fiber‐shaped asymmetric supercapacitors (ASCs) and microbial fuel cells (MFCs). The flexible fiber‐shaped ASC and MFC device based on the N‐MoO3−x anode could deliver an unprecedentedly high energy density of 2.29 mWh cm−3 and a remarkable power density of 0.76 μW cm−1, respectively. Such a bifunctional fiber‐shaped N‐MoO3−x electrode opens the way to integrate the electricity generation and storage for self‐powered sources. High‐performance fiber‐shaped electrodes: A strategy for dual doping with nitrogen and low‐valent molybdenum atoms was used to improve the electrochemical properties of MoO3. The dual‐doped MoO3 nanowires showed exceptional device performances as bifunctional anode materials for both fiber‐shaped asymmetric supercapacitors (ASCs) and microbial fuel cells (MFCs).
