Experimental dataset on tailoring hematite nanodots embedded nitrogen-rich carbon layers for lithium-ion batteries

摘要

The experimental data presented are related to the research article entitled “Nitrogen self-doped carbon sheets anchored hematite nanodots as efficient Li-ion storage anodes through pseudocapacitance mediated redox process” [1]. In brief, the synthesis of nanodotted hematite Fe O embedded in nitrogen-rich carbon layers is achieved through a surfactant-less self-assembly process and it is employed as anodes for Li-ion batteries. The dataset presented depicts the effect of temperature on the phase formation and morphology of the Fe O nanodots and their influence on the electrochemical performance by constructing as anode materials for lithium-ion batteries. Representative XRD patterns, FE-SEM and FE-TEM micrographs, electrochemical potential profiles, and cycling performances for anode materials synthesized by different thermal treatment process are investigated. The shared datasets contribute to clarify the formation temperature and morphological evolution of Fe O into nanodots.
