Spinel lithium manganese oxide, LiMn2O4, prepared by the sol-gel method usi
ng citric acid as a chelating agent under different (i) pH conditions, (ii)
molar ratio of citric acid to total metal ion, (iii) amount of water, (iv)
calcination temperature, and (vi) starting materials. The effects of vario
us synthetic parameters on the purity of this oxide are analysed by means o
f X-ray diffraction measurements. The results show that pure LiMn2O4 can be
prepared from nitrate salts as starting materials at a low temperature of
600 degreesC. The optimum pH and molar ratio of chelating agent to total me
tal ions are 6.0 and 1.0, respectively. (C) 2001 Elsevier Science B.V. All
