Abstract
Official abstract text for this publication.
A lithium-containing oxide having a cubic garnet structure and wherein, when a solid-state 19 F-NMR spectrum is measured under conditions where a 19 F nucleus resonance frequency is 564 MHz, at least one peak is observed within a chemical shift range of −100 to 50 ppm, based on a chemical shift of polytetrafluoroethylene being −122 ppm.
First claim
Opening claim text (preview).
The invention claimed is: 1 . A lithium-containing oxide having a cubic garnet structure, wherein, when a solid-state 19 F-NMR spectrum is measured under conditions where a 19 F nucleus resonance frequency is 564 MHz, at least one peak is observed within a chemical shift range of −100 to 50 ppm, based on a chemical shift of polytetrafluoroethylene being −122 ppm. 2 . The lithium-containing oxide according to claim 1 , wherein, when a solid-state 6 Li-NMR spectrum is measured under conditions where a 6 Li nucleus resonance frequency is 44.1 MHz, at least one peak is observed within a chemical shift range of −5 to 15 ppm, based on a chemical shift of a 1 mol/L LiCl aqueous solution being 1.19 ppm. 3 . The lithium-containing oxide according to claim 1 , wherein, regarding a ratio of the numbers of atoms measured through ICP emission spectroscopy, when La is 3, Li is 5 to 12, and Zr is 1 to 3. 4 . The lithium-containing oxide according to claim 1 , wherein, in a powder X-ray diffraction chart, a peak intensity at 28.5 to 29.0° to a peak intensity at 16.0 to 17.0° is 0.5 or less. 5 . A sintered product comprising the lithium-containing oxide according to claim 1 . 6 . An electrolyte composition comprising the lithium-containing oxide according to claim 1 .
