Abstract

The present application provides a battery. The battery comprises: an electrode assembly; a packaging bag for packaging the electrode assembly; and a plurality of bonding parts, wherein the bonding parts are at least partially arranged at intervals and are positioned between the packaging bag and the electrode assembly. The invention aims to provide the battery capable of reducing the tearing riskof the aluminum foil and improving the safety performance.

Description

technical field [0001] This application relates to the field of power supplies, and more specifically, to a battery. Background technique [0002] Batteries are widely used in electronic products to provide the power they need. Electronic products, especially mobile electronic products, may drop during use, so it is necessary to ensure that battery components will not be damaged under drop conditions. Therefore, during the production process of the battery, the packaging shell and the electrode assembly should be fixed, so as to avoid damage caused by a large mutual displacement during the drop process. [0003] In the current battery production process, the packaging shell and the electrodes inside are bonded together by glue to achieve a firm connection. However, there are still problems such as tearing of the outermost aluminum foil of the electrode assembly during the current drop process, which affects battery safety. Contents of the invention [0004] In view of t...
