Preparation and Characterization of Nano-LiFePO₄/C Using Two-Fluid Spray Dryer

Abstract:

Nano-LiFePO₄/C materials were synthesized by two-fluid spray-drying using FePO₄·2H₂O, LiOH·H₂O as raw materials. The morphology, physical and electrochemical properties of the LiFePO₄/C were tested and analyzed. The morphology of the synthesis LiFePO₄/C was spherical and its aggregated particle size was smaller than 10μm, primary particle size was smaller than 200nm, the tap density of the material up to 1.25g/cm³. The LiFePO₄/C had an initial discharge specific capacity of 163.3mAh/g at 0.1C and its specific capacities were 147.7mAh/g and 121.8mAh/g at 1C and 5C, respectively. The initial charge/discharge efficiency reached 96.6%. Under low temperature 253K, the discharge capacity is 59.6% of that at 298K with 0.2C.
