Abstract:

Energy storage devices are the demand of the new era for flexible portable electronics. Considering the importance of renewable energy and environmental issues. We utilized LiCo_1-xZn_xO₂(x=0.0, 0.1) nanoparticles with an average crystallite size of 31-45nm that were embedded in nanofibers formed by the electrospinning technique. Sol-gel techniques were used to make them. PVP polymer was used as a binder to support the backbone frame of the nanofibers. We have characterized our synthesized material to examine its structural, morphological, and electrical properties. XRD of synthesized material tells us about the rhombohedral structure of the R3m space group symmetry. FTIR spectroscopy was used to study the functional groups and vibrations in synthesized material. SEM results confirmed the formation of nanoparticles embedded in nanofibers. In AC analysis, we have discussed dielectric constant, tangent loss, and AC conductivity. The electrical properties of synthesized LiCo_1-xZn_xO₂(x=0.0, 0.1) nanofibers were studied in a frequency range of 100Hz to 3MHz and found that AC conductivity is high of nanoparticles embedded nanofibers of LiCo_0.9Zn_0.1O₂ i.e., 4.2 x10^-5 (S/m) that plays a crucial role for the supercapacitors and as a cathode material in Lithium-ion batteries(LIBs).
