Title:

POSITIVE ELECTRODE MIXTURE, METHOD FOR MANUFACTURING POSITIVE ELECTRODE MIXTURE, AND LITHIUM-ION BATTERY

Document Type and Number:

WIPO Patent Application WO/2024/043289

Kind Code:

A1

Abstract:

In the present invention, a positive electrode mixture includes an electrically conductive assistant, a sulfur-based active material, and a solid electrolyte, wherein the positive electrode mixture has a 50% or higher rate of overlap in mapping of carbon and phosphorus in an elemental analysis by energy dispersive X-ray spectroscopy of an electron microscope image, and has a diffraction peak A at 2θ=20.2±0.5° and a diffraction peak B at 2θ=41.1±0.8° in a powder X-ray diffraction using CuKα rays.
