Abstract

The present application relates to an electrochemical device and an electronic apparatus. The electrochemical device comprises: a housing; at least part of the electrode assembly is located in the shell; the insulating tape is located between the shell and the electrode assembly, and the insulating tape comprises a first surface bonded with the electrode assembly and a second surface bonded with the shell; the insulating tape meets at least one of the following conditions: a) the first surface comprises a first bonding area with the bonding strength of P1 and a second bonding area with the bonding strength of P2, and 0.2 * P1 < = P2 < = 0.9 * P1; and b) the second surface comprises a third bonding area with the bonding strength of P3 and a fourth bonding area with the bonding strength of P4, wherein P4 is greater than or equal to 0.2 * P3 and less than or equal to 0.9 * P3. The insulating tape can prolong the service life and improve the reliability of an electrochemical device, can reduce the risk that the insulating tape tears an aluminum foil of an electrode assembly in the falling process, and prevents the interior of the electrode assembly from being short-circuited.

Description

technical field [0001] The present application relates to the technical field of energy storage devices, in particular to an electrochemical device and electronic equipment. Background technique [0002] With the development of electronic equipment, the battery of the electronic equipment is required to have a larger capacity, so as to meet the battery life requirement of the electronic equipment. A battery of an electronic device generally includes a case and an electrode assembly inside the case, and the case protects the electrode assembly. Among them, the shell and the electrode assembly can be bonded by insulating tape. When the electronic device falls, the insulating tape may tear the electrode assembly, resulting in an internal short circuit of the electrode assembly. When the insulating tape is not bonded properly, the top seal may break through and other risks, affecting the safety of electronic equipment. Contents of the invention [0003] The present applicati...
