    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.

    摘要： A method for producing an electrochemically advantageous lithium ion-conductive solid electrolyte with high ionic conductivity, low electronic conduction and electrochemical stability is disclosed. The method comprises the steps of synthesizing lithium sulfide by reacting lithium hydroxide with a gaseous sulfur source at a temperature of not less than 130°C and not more than 445°C, thermally melting plural compounds containing at least silicon sulfide and the synthesized lithium sulfide, and cooling the molten mixture. The silicon sulfide is synthesized by the steps of adding a silicon powder to molten sulfur while stirring to disperse the silicon powder in the molten sulfur and heating the silicon powder-dispersed sulfur in a reaction chamber under reduced pressure.
