Synthesis of LiFePO[sub 4] Nanoparticles in Polyol Medium and Their Electrochemical Properties

Abstract

nanoparticles were synthesized using the polyol process without any further heating as a postprocessing step. The X-ray diffraction patterns of the sample exhibited a good fit with the orthorhombic phase with no unwanted impurity phases. The nanoparticles showed a reversible capacity of , which amounts to a utilization efficiency of 98%, with an excellent reversibility in extended cycles. The electrode shows an excellent capacity retention at high-rate current densities due to its single-crystal-like and monodispersed uniform morphology with orthorhombic shape with an average width of and length of .
