Document Type and Number:
WIPO Patent Application WO/2023/145655
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide composite particles for an electrochemical element positive electrode which enable an electrochemical element to exhibit excellent electrochemical properties. Composite particles for an electrochemical element positive electrode in accordance with the present invention comprise a positive electrode active material, a carbon conductive material, and a binder resin, said composite particles being characterized in that the ratio of the carbon atom amount in a center region to the carbon atom amount in an outer region (center region carbon atom amount / outer region carbon atom amount) is 0.3-1.0.
