Description
Summary:•Biowaste-derived carbon is synthesized by a three-step thermal process.•NS-TPPC improves sodium-ion storage properties with a long term cycling stability.•A full-cell of SIB retains 95% of the discharge capacity after 50 cycles.•The heteroatom doped porous structure enhances the electrochemical properties. [Display omitted] Heteroatoms doped porous carbon as anode for sodium ion batteries have been successfully prepared from the bio-waste through a three-step process involving carbonization, activation and doping. The as-prepared nitrogen and sulfur-doped tangerine peel-derived porous carbon delivers a discharge capacity of 377 mAh g1 after 100 cycles at a current density of 50 mA g1 and long-term cycling stability at a current density of 500 mA g1 for 2000 cycles. The interconnected porous structure together with heteroatoms doping enhances the electrochemical storage properties of nitrogen and sulfur-doped tangerine peel-derived porous carbon. Furthermore, a full-cell SIB configuration employing nitrogen and sulfur-doped tangerine peel-derived porous carbon in combination with the Na3V2(PO4)3-C cathode successfully retained 95% of the discharge capacity after 50 cycles. These findings suggest the capability of similar types of biowaste-derived carbonaceous materials with heteroatoms-doping for future large-scale energy storage applications.
