Abstract

LiFePO4-C was prepared by the solid-state reaction using LiH2PO4, Fe2O3, and glucose as raw materials, which is a green and low-cost method. Thermogravimetry, differential scanning calorimetry, X-ray diffraction, and element analyzer were used to study the phase and carbon content of the synthesized samples. The optimum conditions for synthesizing LiFePO4 are identified. The discharge capacity of 120 mAh g−1 was achieved at a current density of 100 mA g−1 between 2.5 and 4.2 V during the first 50 cycles.
