Document Type and Number:
WIPO Patent Application WO/2024/060128
Kind Code:
A1
Abstract:
Provided in the present application are an electrochemical apparatus and an electronic apparatus. The electrochemical apparatus comprises a positive electrode sheet, a negative electrode sheet and a separator, the separator being arranged between the positive electrode sheet and the negative electrode sheet. In the width direction of the separator, the separator has a first area exceeding the positive electrode sheet. The first area comprises a first non-hardened area which projectively overlaps with the negative electrode sheet in the thickness direction of the separator, and a first hardened area which exceeds the edge of the negative electrode sheet in the width direction and is provided with a first hardening agent, the hardness of the first hardened area being greater than 1.0 H, and the hardness of the first non-hardened area being less than 1.0 H. Therefore, the impact resistance of the separator itself is enhanced, thereby allowing it to resist the impact of electrolytes, and further guaranteeing the safety performance when the electrochemical apparatus falls.
