金属有机框架衍生的氮掺杂炭封装铁钴颗粒作为锂离子电池负极材料
A N-doped carbon with encapsulated Fe and Co particles derived from a metal organic framework for use as the anode in lithium-ion batteries
摘要
Abstract
Metal-organic frameworks(MOFs)are import-ant as possible energy storage materials.Nitrogen-doped iron-cobalt MOFs were synthesized by a one-pot solvo-thermal method using CoCl3·6H2O and FeCl3·6H2O dis-solved in N,N-dimethylformamide,and were converted into Fe-Co embedded in N-doped porous carbon polyhedra by pyrolysis in a nitrogen atmosphere.During pyrolysis,the or-ganic ligands transformed into N-doped porous carbon which improved their structural stability and also their electrical contact with other materials.The Fe and Co are tightly bound together because of their encapsulation by the carbon nitride and are well dispersed in the carbon matrix,and improve the material's conductivity and stability and provide additional capacity.When used as the anode for lithium-ion batteries,the material gives an initial capacity of up to 2230.7 mAh g-1 and a reversible capa-city of 1146.3 mAh g-1 is retained after 500 cycles at a current density of 0.5 A g-1,making it an excellent candidate for this purpose.关键词
