Abstract: A lithium ion conductive material has a composition formula of Lia(OH)bFcBr, where 1.8?a?2.3, b=a?c?1, 0.01?c?0.11, and includes an antiperovskite-type crystal phase. Preferably, the lithium ion conductive material further includes a layered antiperovskite-type crystal phase. More preferably, 0?B/(A+B)?0.2 is satisfied, where A is the peak intensity in the vicinity of 2?=31.2° in the X-ray diffractometry using Cu-K? ray and B is the peak intensity in the vicinity of 2?=30.2°.

Abstract: There is provided an all-solid-state lithium battery including: a positive-electrode plate composed of a lithium complex oxide sintered body having a layered rock-salt structure; a solid electrolyte layer composed of a lithium-ion-conductive antiperovskite material; a negative-electrode plate containing Ti and permitting intercalation and deintercalation of lithium ions at 0.4 (vs. Li/Li+) V or more; a positive-electrode current collecting layer provided on a face, remote from the solid electrolyte layer, of the positive-electrode plate; a negative-electrode current collecting layer provided on a face, remote from the solid electrolyte layer, of the negative-electrode plate; a positive-electrode covering metal membrane provided at an interface between the positive-electrode plate and the solid electrolyte layer; and a negative-electrode covering metal membrane provided at an interface between the negative-electrode plate and the solid electrolyte layer.

Abstract: A solid electrolyte is constituted by lithium phosphorus oxynitride (LiPON). A multiplication value obtained by multiplying a ratio of a peak intensity of nitrogen atoms having a single bond with one P atom and having a double bond with another P atom to a peak intensity of an N2 state in a Raman spectroscopy spectrum by a ratio of a content amount of N atoms to a content amount of P atoms is greater than or equal to 0.40.
