摘要：

A simple, low-cost, adipic acid-assisted, solid-state method was used to prepare carbon-coated, nanocrystalline LiFePO4 material. Scanning electron microscopy (SEM) images revealed that the majority of the particles lay between 200 and 400 nm for pure LiFePO4, while the carbon-coated LiFePO4 particles were sized from 70 to 250 nm. Cycling studies indicated a high and stable discharge capacity of 150 mAh g(-1) for the Li/carbon-coated nanocrystalline LiEePO(4) at room temperature. High rate capability studies from 0.5C to 20C demonstrated an excellent capacity retention efficiency of over 99.9%. (C) 2010 Elsevier B.V. All rights reserved.
