| Abstract: | Abstract LiFeO2, with a layered rocksalt structure of α-NaFeO2-type was prepared by ion exchange reaction from Na+ ion to Li+ ion using α-NaFeO2. α-NaFeO2-type LiFeO2 was synthesized by using the mixture of LiI and KI in the temperature range 220 to 480 °C. The heat treatment temperature of 600 °C gave α-LiFeO2-type LiFeO2 as a main product. As a result of Rietveld analysis, the structure of LiFeO2 which assigned to α-NaFeO2-type by an XRD measurement, was the mixture of α-NaFeO2-type and Li-intercalated spinel-type structures. |
