Abstract
A core-sheath structured carbon nanofiber@nitrogen-doped porous carbon (CNF@NPC) composite is synthesized as a promising anode material for sodium-ion batteries (SIBs). Particularly, the eco-friendly bacterial cellulose (BC) is used as both template and precursor for the synthesis of CNF@NPC through the carbonization of bacterial cellulose@polypyrrole (BC@PPy). Due to the particular core-sheath structure and the synergetic effect between the CNF core layer and the NPC outer layer, the CNF@NPC exhibit outstanding electrochemical performance, including a high reversible specific capacity (240 mAh gâ1 at 100 mA gâ1 over 100 cycles), excellent rate performance (146.5 mAh gâ1 at 1000 mA gâ1), and superior cycling stability (148.8 mAh gâ1 at 500 mA gâ1 over 400 cycles). The application of environmentally friendly electrode material may open a new situation for SIBs.
