OXIDE-BASED POSITIVE ELECTRODE ACTIVE MATERIAL AND USE OF SAME

Document Type and Number:

WIPO Patent Application WO/2023/095889

Kind Code:

A1

Abstract:

The present invention addresses the problem of providing a novel oxide-based positive electrode active material having exceptional charge/discharge characteristics. The aforementioned problem is solved by an oxide-based positive electrode active material that is a glass ceramic configured to include: Li or Na; at least one transition metal (groups 3 to 12 in periods 4 and 5); and ions selected from the group consisting of sulfate ions, silicate ions, aluminate ions, germanate ions, borate ions, nitrate ions, carbonate ions, and halide ions.
