LiFePO4 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 LiFePO4 nanoparticles showed a reversible capacity of 166 mAh/g, 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 20 nm and length of 50 nm.
