Kolkovskyi P. Obtaining, structure and electrochemical properties of fluoride nanodispersed iron

The thesis are presented the results of a comprehensive comparative analysis of the process of thermal decomposition of iron trifluoride trihydrate in different atmospheres and established the main determining factors: atmosphere type, annealing method, heating rate, annealing temperature and time of exposure at a given temperature. B-FeF3 o 3H2O crystallographic structure basis has been clarified. There was defined particle size range of critical material for r-FeF3 phase which is a second kind phase transition of superparamagnetic state - magnetically ordered state. A testing of hydrated and anhydrous forms trifluoride iron nanocomposites type hydrated form / anhydrous form FeF3 and nanocomposites based on phase r-FeF3 with the inclusion of hematite as the cathode compositions LPS have been tested. It was clarified the effect of individual component performance composites LPS and showed the suitability of the submissions received the use of secondary sources of supply. The effect of process changes on intercalation phase composition, transformation of crystalline and magnetic microstructure of cathode materials has been experimentally studied. Formation phase of garnet structure with predictable composition Li6Fe2F12 in intercalated cathodes based on iron fluoride has been registered. It was established that the intercalation process in the studied material occurs by a similar mechanism and accompanied by amorphization cathode materials.
