LiCrO. 1 5CoO.850Z nanowires were prepared successfully by electrospinning technique at the calcination temperature of 500 ·C for 6 hours. The average diameter of the nanowires was 45 nm. The phase transformation, crystallite structure and morphology of the prepared LiCrO.lSCoO.8S02 nanowires were studied using thermal analysis, X-ray diffraction / FTIR spectroscopy and scanning electron microscope analysis, respectively. The crystalline phase of the sample was identified as a single phase with a-NaFeOz type structure and the peaks were indexed to the hexagonal system assuming the R3 m symmetry.The electrochemical behavior of the prepared LiCrO. 1 5CoO.850Z nanowires based electrode was investigated by cyclic voltammetry and AC-impedance studies. The electrochemical measurements provided a maximum specific capacitance of 77.7 Fg· 1 with a resistivity of 4.50. Finally, the asymmetric supercapacitor cell AC// LiCrO.lSCoO.8S02 was fabricated and its specific discharge capacitance, energy density and power density were determined are found to be 72.3 Fg· 1 , 256.2 Wkg-1 and 183.5 Wh kg-I , respectively. The cell has good cycling stability and retaining 94 % of its initial charge even after 1000 cycles. It revealed that the prepared LiCrO. 1 5CoO.8502 nanowires could be used as an effective electrode material for high performance asymmetric supercapacitors.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
