Hierarchically Well‐Developed Porous Graphene Nanofibers Comprising N‐Doped Graphitic C‐Coated Cobalt Oxide Hollow Nanospheres As Anodes for High‐Rate Li‐Ion Batteries

Abstract: Hierarchically well‐developed porous graphene nanofibers comprising N‐doped graphitic C (NGC)‐coated cobalt oxide hollow nanospheres are introduced as anodes for high‐rate Li‐ion batteries. For this, three strategies, comprising the Kirkendall effect, metal–organic frameworks, and compositing with highly conductive C, are applied to the 1D architecture. In particular, NGC layers are coated on cobalt oxide hollow nanospheres as a primary transport path of electrons followed by graphene‐nanonetwork‐constituting … Show more

“…In the N 1s XPS spectrum (Figure 4E), the pyrrolic-N at 400 eV, graphitic-N at 400.9 eV, and oxidized-N species at 401.9 eV are detected. 26,39 These peaks confirm N-doping into carbon. Raman spectroscopy is analyzed as shown in Figure 4F to confirm the crystallinity of the carbon material of A300NF.…”

“…2-mIM, as an organic linker of Fe@ZIF-67, acts as an Ndoping source under N 2 atmosphere. 25,26 Further, during carbothermal reduction, metallic Co and CoFe crystals play the role of catalysts for the graphitization of carbon formed by PAN. 25,26 Thus, carbonization of both the organic linker of Fe@ZIF-67 and PAN into graphitic carbon (GC) doped with N leads to metallic Co and CoFe nanospheres coated with N-doped GC (N-GC) in the structure.…”

“…The use nitrogen-doped rGO (N-rGO) is a promising strategy for the development of anode materials for LIBs with high electrochemical performance [491,492]. Li et al [492] Hierarchically well-developed porous graphene nanofibers comprising N-doped graphitic carbon (NGC)-coated cobalt oxide hollow nanospheres were tested as anodes for high-rate Li-ion batteries [493]. This nanostructured composite delivers a discharge capacity of 823 mAh g −1 after 500 cycles at 3.0 A g −1 current density with a low decay rate of 0.092% per cycle.…”
