Abstract
The data presented in this article are related to the research article entitled "New synthesis strategy for hollow NiO nanofibers with interstitial nanovoids prepared via electrospinning using camphene for anodes of lithium-ion batteries" [1]. Hollow NiO nanofibers were prepared by electrospinning process using camphene and subsequent heat-treatment process with various temperatures. The data presented in this manuscript showed the effect of the heat-treatment temperature of the as-spun fibers on the lithium ion storage properties of the hollow NiO nanofibers as anodes for lithium ion batteries. Each FE-SEM image, XRD pattern, cycle, and rate properties of the hollow NiO nanofibers obtained at various heat-treatment temperatures were investigated.
