Novel Hollow NiO@Co₃O₄ Nanofibers for High-Performance Supercapacitors.

NiO@Co3O4 nanofibers with different mass ratio and different additives were prepared by electrospinning process. The characterizations of the nanofibers are investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Electrochemical properties are characterized by cyclic voltammetry, galvanostatic… CONTINUE READING
