    摘要： A method of synthesizing a lithium iron oxide applicable for an active material of lithium batteries is disclosed. The method includes a step of heating a starting material, which comprises an iron(III) oxyhydroxide and a lithium compound, in a water vapor-containing atmosphere to yield a lithium iron oxide. An example of the iron(III) oxyhydroxide is γ-FeOOH, whereas any one or mixture of Li 2 O, LiOH, and LiOH·H 2 O is used as the lithium compound. The heating temperature is not higher than 350°C and the water vapor pressure is lower than the saturated water vapor pressure at the heating temperature. The method preferably includes a step of immersing the reaction product obtained by the heating step in water having a temperature of not higher than 30°C.
