제목 The Effects of Fabrication Condition on the Microstructures and Electrochemical Properties of LaMnO3 nanofibers
초록 Recently, metal oxides with perovskite structure as electrode materials for energy storage devices have attracted significant attention from industry and academia because of their high specific capacitance. In this study, lanthanum manganate (LaMnO3) nanofibers were fabricated by electrospinning and calcination processes to improve the energy density. The morphology and microstructural features of the nanofibers were characterized by electronic microscopy and X-ray diffraction method. The specific surface areas and pore size distribution of the nanofibers were also measured by using BET measurement. To evaluate the electrochemical characteristics of the LaMnO3 nanofibers, cyclic voltammetry and galvanostatic charge–discharge measurements were carried out. In addition, the electrochemical impedance spectroscopy was adopted to characterize the ion diffusion kinetics and interfacial resistance along with LaMnO3 nanofibers in electrolyte systems.
