| Summary: | Lithium iron phosphate (LiFePO4) is a cathode material for the
rechargeable-lithium batteries. In this paper is presented a novel method of
fabrication carbon-coated LiFePO4 in a pilot reactor built according to the
principles of the thermo-acoustic burner of Helmholtz-type. Crystalline
powder with a high percentage of LiFePO4 was synthesized by incomplete
combustion, i.e. in the reductive atmosphere, and calcined at 700°C for 6
h. The obtained samples were characterized by X-ray diffraction, IR and
Raman spectroscopy. The aim of this study was to demonstrate the production
of the high-quality lithium-ion cathode material by the incomplete
combustion. The synthesis of LiFePO4 is completed during calcination and an
ordered structure is attained. Fast synthesis in the reactor (less than 2 s)
is achieved due to the reduction in the size of reactant's particles and a
huge number of collisions owing to their strong turbulent flow associated
with explosive combustion. [Project of the Serbian Ministry of Education, Science and Technological Development, Grant no. III 45003] |
