A METHOD OF PREPARING AN ELECTRODE MATERIAL FOR LITHIUM-ION BATTERIES

The present invention discloses a method of preparing an electrode material for lithium-ion batteries comprising the steps of preparing a mixture of precursors taken in predefined stoichiometric ratios for synthesis of lithium iron phosphate (LiFePO4), adding niobium pentoxide as a precursor for doping of niobium at Li+ site of LiFePOfor synthesis of niobium doped LiFePOand ball milling operation provides nano sized powder particles. Now, a precursor of carbon is added to said mixture of precursors for synthesizing and obtaining carbon coated niobium doped LiFePOnano sized powder particles. Pellets of required size are prepared and sintered. The obtained pellets are structurally characterized.
