WIPO Patent Application WO/2022/230426
Kind Code:
A1
Abstract:
One embodiment of the present invention pertains to a lithium ion conducting oxide or an all solid battery, said lithium ion conducting oxide having a crystal structure based on LiTa2PO8, containing at least lithium, tantalum, boron, phosphorus, oxygen and fluorine as the constituent elements thereof, having a boron content represented by formula (1) of 4.0-15.0%, and having a fluorine content represented by formula (2) of 0.5-2.0%. (1): Number of B atoms/(number of B atoms + number of P atoms) × 100
(2): Number of F atoms/(number of O atoms + number of F atoms) × 100
