Comparative Characteristics of the Li–Fe–O and Li–Fe–Р–O Powders Obtained by Pyrolytic Extraction

The structural and optical properties of lithium–iron oxide and lithium–iron–phosphorus oxide obtained by pyrolytic extraction are compared using X-ray diffraction, vibrational spectroscopy, and Raman spectroscopy. The conditions for the formation of crystalline phases of these disperse materials are established. Using methods of spectroscopy, the material is demonstrated to contain carbon, improving the mobility of electrons.
