Аннотация:Carbon-coated composites based on LiFePO4 with the olivine structure have been prepared by thePechini method. The materials have been characterized by X-ray diffraction, scanning electron microscopy,thermogravimetric analysis, and Raman spectroscopy. Optimizing the LiFePO4 precursor heat treatmentconditions, we have obtained LiFePO4 with the olivine structure and a primary particle size of ~30 nm. Onthe addition of 0.2 wt % silver to the composite, a cathode material with improved electrochemical performance has been obtained. The discharge capacity of the resultant material at cycling current densities of 20 (C/8), 1600 (10C), and 3200 mA/g (20 C) is 166, 85, and 53 mAh/g, respectively.
