摘要
Carbon materials as promising anodes for lithium ion batteries (LIBs) have attracted great attentions owing to their high theoretical capacities and rich natural resources. To improve anode performance of carbon, several common strategies have been developed, such as the fabrication of carbon with various nanostructures and modification of carbon frameworks by heteroatoms doping. Besides, the introduction of transition metal single atom or atom clusters embedded in nitrogen-doped carbon frameworks is also a feasible route. Herein, we report a simple and effective approach for synthesis of Co-n@N-C hybrids (i.e., Co@N-C-0, Co-n@N-C-1 and Co-n@N-C-2) with interconnected porous carbon nanostructures and numerous active sites (e.g., Co-N-C). When it was measured as anode for LIBs, the Co-n@N-C-1 hybrid displayed outstanding lithium storage properties with a high initial reversible capacity of 1587 mAh g(-1) at 0.1 C and maintained a high reversible capacity of 1000 mAh g(-1) at 5 C after 800 cycles. Both experimental and theoretical results reveal that Co-N-C with high specific activity along with interconnected porous carbon nanostructures synergistically promote the transportation and storage of Li+.
