Abstract
A simple, versatile nonaqueous sol-gel method for the synthesis of carbon-coated as high-performance cathode is reported. The method consists of two simple steps: dissolve lithium acetate, iron(II) acetate and phosphoric acid in ethylene glycol to form a molecularly homogeneous, monolithic organo-gel and directly heat the gel in nitrogen atmosphere to form carbon-coated, phase-pure The formed consists of 200-300 nm particles with rather uniform size distribution and with 1-4 wt % surface carbon coating formed in situ. The favorable physical characteristics of the synthesized give rise to excellent rate performance. © 2004 The Electrochemical Society. All rights reserved.Keywords
