The electronic environment and physicochemical property of carbon materials can be easily tailored and modulated by heteroatom doping. Herein, we demonstrate that net‐like N, O, S triple‐doped microporous carbon nanowires (NOS‐MCNs) as an anode can be designed to improve the electrochemical performance of sodium ion batteries. Ammonium persulfate as oxidant can also provide a nitrogen and sulfur source for S‐containing PPy. The N, O and S atoms are introduced into the carbon skeleton with activation and carbonization processes to modify the surface properties. As an anode, the material exhibits a high specific capacity and a long lifespan (≈301 mA h g −1 at 0.2 A g −1 after 1000 cycles) as well as an excellent rate capability (158 mA h g −1 at an extremely high current density of 10 A g −1 ). This work offers a facile strategy to synthesize triple‐doped porous carbon materials for sodium ion batteries and other energy‐storage fields.
