Nanosized lithiated iron oxides with 10 and 50 wt.% SiO2 were prepared by a sol–gel method using 1 M Fe(NO3)3 · 9H2O and 1 M LiNO3 aqueous solutions in a stoichiometric ratio of 1:1 and colloidal silica. Dried xerogel was calcinated at 700 °C for 4 h in air. The X-ray data of samples synthesized using 10% and 50% SiO2 showed the presence of a mixture of two phases: α-LiFeO2 and Li1−xFe5O8 (0 < ...
