A synthesis strategy for hollow and porous nanofibers comprising hollow NiO (H-NiO) nanospheresformed via nanoscale Kirkendall diffusion and supported over a porous graphitic carbon matrix (HNiO@HNFs) is reported herein to enable the fabrication of advanced anodes for stable lithium-ion batteries(LIBs). The H-NiO@HNFs comprising 1D longitudinal hollow channels ensured efficient diffusion ofcharged species via effective electrolyte percolation besides providing sufficient space to accommodatethe large volume variations during repeated cycling. The hollow NiO nanospheres acted as chemical sitesfor lithiation and delithiation. Additionally, the H-NiO@HNFs exhibited improved lithium-ion storageproperties, such as reasonable rate capability, stable prolonged cyclability at a high current density(1.0 A g-1), and a high lithium-ion diffusion coefficient, primarily owing to their enhanced structuralintegrity compared to that of filled NiO nanofibers (F-NiO NFs). This facile synthesis approach couldbroaden the current understanding of 1D hollow nanostructures decorated with conventional hollowmetal-oxide nanoparticles for various applications.
