Heteroatoms doped porous carbon derived from bio-waste shows improved electrochemical storage properties and long-term cycling stability. The nitrogen and sulfur doping, along with the interconnected porous structure, enhance the performance of the carbon material for sodium ion batteries.
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 g(1) after 100 cycles at a current density of 50 mA g(1) and long-term cycling stability at a current density of 500 mA g(1) 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. (C) 2021 Elsevier B.V.
