Synthesis and spectroscopic characterisation of LiFePO4 cathode materials

Lithium iron phosphate (LiFePO4) are synthesized in complete and incomplete combustion and calcined at 700 degrees C. The obtained samples were characterized by XRD, IR spectroscopy and magnetic measurement. Morphology of samples was controlled by SEM. The aim of this work is to show that it is possible to achieve a desired crystal phase by pulse combustion in a relatively cheap and fastway. The extremely rapid synthesis of almost pure phase material is possible due to the reduction in size of interacting particles and to an enormous number of collisions between them as a result of the strong turbulent flow associated with explosive combustion.
