    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.degree. C. and not more than 445.degree. 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.

    摘要: A lithium secondary battery free from problems encountered with a positive electrode active material exhibiting an electrode potential of not lower than 4.5 volts versus Li—a deterioration in performances because of self-discharge with decomposition of the electrolyte. The lithium secondary battery uses a sulfide based lithium ion conductive solid electrolyte as the electrolyte. Thus, a lithium secondary battery with a very low self-discharge tendency, that is, with the decomposition of electrolyte highly controlled, can be obtained even using the positive electrode active material generating a high voltage.
