Title:
ELECTROCHEMICAL APPARATUS AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/168585
Kind Code:
A1
Abstract:
An electrochemical apparatus and an electronic device. The electrochemical apparatus comprises an electrode, wherein the electrode comprises a current collector (10) and an active material layer (50) located on one side or two sides of the current collector (10); the surface of the active material layer (50) is provided with a hole-shaped structure (40); and the results of a thermogravimetric analysis test performed on the active material layer (50) and conducted in an inert atmosphere at a heating speed of 10ºC/min show that the mass of the active material layer (50) changes from 0% to 0.2% at 350ºC to 800ºC. The electrode can improve the energy density and the dynamic performance, thereby improving the rate capability.
