X-Ray Diffraction and Electric Measurements of Phase Transformation in Li-Mn Spinels
Laboratory prepared and commercial Li-Mn spinels were studied. Making use of the dedicated XRD-impedance spectroscopy experimental set-up, direct correlations of the degree of phase transformation (expressed as change of the FWHM of the selected reflection) with electric conductivity was found. Independent XRD measurements and full pattern fitting allowed quantitative estimations of the phase composition of the spinels. It was found that commercial spinels were in fact multiphase, with the content of the additional phase of few weight percent.
