Li2CO3, FeC2O4·2H2O, Mn(COOCH3)2·4H2O and NH4H2PO4 (all
chemicals of 99% purity from Aldrich) and citric acid (Shinyo Pure
Chemicals, 99% purity) were used as the starting materials to synthesize
LMFP composites. These were dissolved in deionized water
at room temperature and to the resulting solution was added citric
acid solution. After homogenous mixing, the sol was dried by
keeping it at 75 ◦C for 12 h during magnetic stirring.
