Interconnected porous N-doped carbon coated cobalt/iron oxides core shell nanocomposites for superior lithium storage anode

Carbon encapsulated hybrid Fe-based nanostructure with durable lithium storage

“…14 To overcome these problems, organic materials have been used as carbon sources, such as glucose, furfuryl alcohol, citric acid, ionic liquids, oleic acid, ethylenediaminetetraacetic acid (EDTA) and ethylene glycol. 15 For instance, the reported magnetite-C nanocomposites was prepared from furfuryl alcohol 16 and the porous nitrogen doped carbon coated Fe/ Co oxide nanocomposites was obtained from glucose/urea, 17 which both possessed high capacity and capacity retention. Based on previous work, nitrogen doping can efficiently improve the cycle performance and rate capacity of the composites, which would be beneficial to improving the electronic conductivity, ion permeability of the carbon layer, interfacial charge transfer and stability.…”
