抄録

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.
