A series of carbon-coated olivine phase (C–LiFePO 4 ) was synthesized under argon by mechano-chemical activation, with two thermal-treatments (“slow” or “fast”) and two temperatures (575 °C or 800 °C). In spite of similar chemical and structural properties, they showed rather good, but very different, electrochemical behaviors in long range cycling or high rate conditions. All the studied...
C–LiFePO 4 composites were synthesized by mechano-chemical activation using iron and lithium phosphates, and also cellulose as carbon precursor; this mixture was treated with 2 thermal treatments (“slow” or “fast” treatment) and 2 temperatures (575 °C or 800 °C). The four synthesized samples were pure olivine-type materials (XRD), but chemical analyses and Mössbauer spectroscopy show Li/Fe...
