Fine Lithium Iron(II) Phospho-Olivine Prepared by Different Methods

Abstract:

The electroactive materials LiFePO4, Li0.98Mg0.01FePO4 and carbon-coated LiFePO4 were synthesized by an improved solid-state reaction and by a sol-gel process and characterized by XRD, SEM, and their electrochemical performance. The reaction conditions favor stabilization of the iron as Fe2+ as well as offering some control of the product morphology and particle size. Electrochemical evaluation of the products reveals a lithium insertion plateau around 3.4V vs Li. Excellent electro- chemical properties in terms of capacity, reversibility and cycling stability have been achieved for doped LiFePO4 synthesized by an improved solid-state reaction. The two methods all produced pure, fine and homogeneous particles.
