摘要： The present invention provides a manufacturing method suitable for manufacturing, in large amounts, an ionic conductor that is superior in terms of various properties such as ion conductivity. According to one embodiment of the present invention, provided is a method for manufacturing an ionic conductor, said method including: mixing, using a solvent, LiBH4 and a lithium halide represented by formula (1), LiX (1) (in formula (1), X represents one selected from the group consisting of halogen atoms); and removing the solvent at 60-280° C. Ionic conductors obtained with this manufacturing method can be used as, for example, solid electrolytes for all-solid-state batteries.

摘要： One embodiment provides a solid-state battery that has a positive-electrode layer; a negative-electrode layer; and a lithium-ion-conducting solid electrolyte layer disposed between the positive-electrode layer and the negative-electrode layer. The positive-electrode layer contains a positive-electrode active material and a solid electrolyte comprising a hydride of a complex. Said positive-electrode active material is sulfur-based, and the solid electrolyte layer contains a solid electrolyte comprising a hydride of a complex.
