Iron doped/undoped LiCoO2 powders could be obtained from hydrothermal reactions of either Fe3+ or Co3+ containing co-precipitates or a CoCl2- NaOH-NaClO3 (oxidant) mixture with an excess amount of LiOH·H2O at 220 °C for 8-48 h. The LiFe(x)Co(1 - x)O2 solid-solution maintained a layered rock- salt structure until x = 0.25. 57Fe Mossbauer and Co K-edge XANES spectra and magnetic susceptibility data reveal that iron and cobalt in the solid solution are in high-spin Fe3+ (S = 5/2) and low-spin Co3+ (S = 0) configurations.
