ELECTROCHEMICAL APPARATUS AND ELECTRONIC DEVICE

WIPO Patent Application WO/2023/225849

A1

The present application discloses an electrochemical apparatus and an electronic device. The electrochemical apparatus comprises a positive electrode sheet, the positive electrode sheet comprises a positive electrode active material layer, and the positive electrode active material layer comprises a first material and a second material; in a fully charged state of the electrochemical apparatus, in an XRD diffraction pattern of the positive electrode sheet, a diffraction peak A1 of a crystal face of the first material (111) and a diffraction peak B1 of a crystal face of the second material (003) exist within a range of 18° to 20°. The electrochemical apparatus of the present application can have improved high-temperature cycle performance.
