LiFePO4 samples were prepared in a modified sol-gel process. The resulting LiFePO4 xerogels were ground and mixed with 2 wt.% of selected carbon components (graphite flakes and carbon nanotubes) in a ultrasonic cleaner. As-prepared composite samples were isostatically pressed at ca. 8 GPa and elevated temperatures (400, 800 or 1000 degrees C) in order to provide more intimate contact between small grains of LiFePO4 and the carbon components. The as-synthesized LiFePO4 material and its composites with carbon were characterized by a number of methods: X-ray diffractometry (XRD), differential scanning calorimetry-thermogravimetry (DSC-TGA), scanning electron microscopy (SEM). Raman spectroscopy. Mossbauer spectroscopy and impedance spectroscopy (IS). It was confirmed that synthesized material contains only a triphylite phase. The presence of carbon does not affect the crystalline structure of the parent material. The conductivity of such composites was high - over 10(-3)S cm(-1) at room temperature. The composites have not been tested yet in electrochemical cells. (C) 2011 Elsevier B.V. All rights reserved.
