According to one embodiment of the present invention, provided is an ionic conductor comprising lithium (Li), borohydride (BH), phosphorus (P), and sulfur (S), wherein, in X-ray diffraction (CuK&#x3b1;: &#x3bb;=1.5405 &#x212b;), the ionic conductor has diffraction peaks, at least, at 2&#x3b8;=14.4&#xb1;1.0 deg, 15.0&#xb1;1.0 deg, 24.9&#xb1;1.0 deg, 29.2&#xb1;1.5 deg, 30.3&#xb1;1.5 deg, 51.1&#xb1;2.5 deg and 53.5&#xb1;2.5 deg.

Ionic conductor and method for producing the same

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.
