Herein, we develop a surface-reinforced self-supporting fiber electrode the simple-yet-reliable ink-extrusion technology to introduce a thin polymer layer at the electrode surface, which endows the fiber architecture with sufficient rigidity for the subsequent fiber cell assembly. Such fiber LiFePO//LiTiO full cells exhibit high linear capacity output (0.144 mA h cm) and energy density (0.267 mW h cm).
