Electrochemical performance of heteroatom-enriched amorphous carbon with hierarchical porous structure as anode for lithium-ion batteries
چکیده انگلیسی
Heteroatom-enriched amorphous carbon with hierarchical porous structure (HAC-HPS) was prepared for use as anode material for Li-ion batteries. The prepared HAC-HPS had open macroporous structure with a large number of nanopores and exhibited a high specific surface area of 1265.9 m2/g. In addition, the prepared HAC-HPS had numerous heteroatoms, with 9.8 at% oxygen, 7.3 at% nitrogen, and 7.6 at% sulfur. The HAC-HPS showed superior electrochemical performance, including a high reversible capacity of 935 mAh/g, good rate performance, and great cycle stability over 275 cycles. The specific capacity increased continuously and reached 1090 mAh/g by the 270th cycle.
