FeF 3 ⋅ 0.33H 2 O is considered as a potential candidate cathode material owing to the special structure with one‐dimension (1D) tunnel. However, its practical application is hindered by the poor electric conductivity. In this work, FeF 3 ⋅ 0.33H 2 O embedded into N, S co‐doped porous carbon (NSPC) derived from antibiotic bacterial residues was synthesized by a facile wet‐impregnation method. Close contact of FeF 3 ⋅ 0.33H 2 O nanoparticles with NSPC can provide the rapid electron conduction channel and keep the structural stability, which endows that FeF 3 ⋅ 0.33H 2 O@NSPC electrode achieves excellent cycling performance with a reversible capacity of 164.5 mAh g −1 at 40 mA g −1 after 100 cycles between 2.0 and 4.5 V and good rate performance. This study offers a new method for high‐value utilization of antibiotic bacteria residues (ABRs) for application in energy storage.
