Abstract
Official abstract text for this publication.
According to one embodiment of the present invention, provided is an ionic conductor comprising lithium (Li), borohydride (BH 4 − ), phosphorus (P), and sulfur (S), wherein, in X-ray diffraction (CuKα: λ=1.5405 Å), the ionic conductor has diffraction peaks, at least, at 2θ=14.4±1.0 deg, 15.0±1.0 deg, 24.9±1.0 deg, 29.2±1.5 deg, 30.3±1.5 deg, 51.1±2.5 deg and 53.5±2.5 deg.
First claim
Opening claim text (preview).
The invention claimed is: 1. An ionic conductor comprising lithium (Li), borohydride (BH 4 − ), phosphorus (P), and sulfur (S), wherein, in X-ray diffraction (CuKα: λ=1.5405 Å), the ionic conductor has diffraction peaks, at least, at 2θ=14.4±1.0 deg, 15.0±1.0 deg, 24.9±1.0 deg, 29.2±1.5 deg, 30.3±1.5 deg, 51.1±2.5 deg and 53.5±2.5 deg. 2. A method for producing an ionic conductor, which comprises mixing LiBH 4 and P 2 S 5 at a molar ratio of LiBH 4 : P 2 S 5 =x: (1−x) [wherein x is greater than 0.85 and 0.98 or less] to obtain a mixture, and subjecting the mixture to a heat treatment, wherein the ionic conductor comprises lithium (Li), borohydride (BH 4 − ), phosphorus (P), and sulfur (S), and has diffraction peaks, at least, at 2θ=14.4±1.0 deg, 15.0±1.0 deg, 24.9±1.0 deg, 29.2±1.5 deg, 30.3±1.5 deg, 51.1±2.5 deg and 53.5±2.5 deg in X-ray diffraction (CuKα: λ=1.5405 Å). 3. The method for producing an ionic conductor according to claim 2 , wherein the temperature applied in the heat treatment is 50° C. to 300° C. 4. The method for producing an ionic conductor according to claim 3 , wherein the temperature applied in the heat treatment is 60° C. to 200° C. 5. The method for producing an ionic conductor according to claim 2 , wherein the mixing is carried out in an inert gas atmosphere. 6. A solid electrolyte for all-solid-state batteries, comprising the ionic conductor according to claim 1 . 7. An all-solid-state battery comprising the solid electrolyte for all-solid-state batteries according to claim 6 . 8. The method for producing an ionic conductor according to claim 3 , wherein the mixing is carried out in an inert gas atmosphere. 9. The method for producing an ionic conductor according to claim 4 , wherein the mixing is carried out in an inert gas atmosphere.
