Document Type and Number:
WIPO Patent Application WO/2022/210482
Kind Code:
A1
Abstract:
A solid electrolyte according to the present invention includes, as a main component, a component where, using values a-f that are larger than 0, the compositional formula thereof is represented by Lia+dMbXcAeOf (wherein, M is an element that is trivalent when a cation, X is a halogen element, and A is elemental sulfur or elemental phosphorus), and 0.8c≤(a+3b)≤1.2c and 1.6f≤(d+n×e)≤2.4f (wherein, n is 4 or 6 when A is elemental sulfur, and n is 5 when A is elemental phosphorus) are satisfied. As a result, it is possible to provide a solid electrolyte having high temperature stability and high lithium ion conductivity.
