摘要：
LiFePO4 nanoparticles were synthesized via polyol process. The temperature of the solution was rapidly increased up to 320 degrees C to obtain larger particles and the temperature was maintained for 16 h in a round-bottomed flask attached to a refluxing condenser. The Xray diffractrion (XRD), pattern was indexed on the basis of orthorhombic olivine structure. The LiFePO4 compound prepared through polyol process exhibited a high crystallinity. The particles show the various shapes with size ranging from 100 to 300nm. The initial discharge curve of LiFePO4 capacity shows 168 mA h/g at the 0.1 C rate in the voltage range of 2.5-4 V with well-formed plateau. (c) 2007 Elsevier Ltd. All rights reserved.
