VARGAS, Max et al. ELECTROCHEMICAL BEHAVIOR OF LiFePO₄ / C IN FUNCTION OF PARTICLE SIZE, SYNTHESIZED BY THE HYDROTHERMAL ROUTE. Rev. Bol. Quim [online]. 2014, vol.31, n.2, pp.103-109. ISSN 0250-5460.

LiFePO₄ material was prepared by hydrothermal method at a temperature of 170°C, using Li₂CO₃, LiAc, LiOH as precursors for lithium, and FeSO₄5H₂O and H₃PO₄ as precursors for Fe and P, the solution pH was set according to the lithium precursor used. The structural characterization was carried by XRD, SEM, TEM technics. A single crystalline phase was identified and a particle size ranged between 20 and 0.5um was observed for the different lithium precursors. The electrochemical characterization shows a discharge capacity of 130 mAh/g for the LiOH lithium precursor synthetized material.
