A new lithium iron phosphate LiFe2P3O10 synthesized at 600 degrees C from precursor obtained by wet chemistry

Abstract : We present the synthesis and characterization of a novel lithium iron polyphosphate LiFe2P3O10 prepared by wet-chemical technique from nitrate precursors. The crystal system is shown to be monoclinic (P2(1)/m space group) and the refined cell parameters are a=4.596 angstrom, b=8.566 angstrom, c=9.051 angstrom and beta=9-97.46 degrees. LiFe2P3O10 has a weak anti ferromagnetic ordering below the Neel temperature T-N=19 K. Electrochemical measurements carried out at 25 degrees C in lithium cell with LiPF6-EC-DEC electrolyte show a capacity 70 mAh/g in the voltage range 2.7-3.9 V.
