Revealing the mechanism of reductive, mechanochemical li recycling from lifepo4

TechnicalRemarks: X-ray powder diffraction (XRD): Data was processed using WinXPow to transform the obtained .raw data into .xy data avoiding negative intensities. Data was plotted using OriginLab. 57Fe Mössbauer spectroscopy: The spectra were fitted with WinNormos and plotted using OriginLab. X-ray absorption spectroscopy (XAS): All XAS spectra were analyzed and processed utilizing the ATHENA software package. The X-ray absorption near edge spectra (XANES) regions of the XAS spectra were acquired by subtracting the pre-edge background from the overall absorption and normalizing to the spline fit using the ATHENA software package.
