In this work we have investigated possibility to obtain pure LiFePO4 powder using different organic additives during hydrothermal synthesis at 180°C. Phase pure phospho olivine was obtained in presence of polyvinylpyrrolidone, while addition of polyvinyl alcohol leads to formation of LiFePO4 with impurities. Impurity phase was successfully avoided by introducing citric acid into reaction vessel. Phase composition was determined by XRPD. Morphology was revealed by particle size analyzer and FESEM.
