摘要：

High performance nanocrystalline LiFePO4 was successfully synthesized utilizing a solid-state method with adipic acid as the carbon source Different molar ratios of adipic acid to total metal ions were analyzed which Included the mol ratios 0 005 0 1 and 02 Among the different concentrations tests 0 1 mol adipic acid-treated LiFePO4 exhibited superior performance in terms of capacity profile and a stable discharge behavior of similar to 150 mAh/g at room temperature The thickness of the carbon coating layer was confirmed at approximately 5 nm by transmission electron microscopy Rate capability studies were also performed from 1 0 to 37 C for 0 1 mol adipic acid-treated LiFePO4 These studies clearly showed excellent capacity retention over 73 mAh/g at 37 C rate Crown Copyright (C) 2010 Published by Elsevier B V All rights reserved
