WIPO Patent Application WO/2023/006051
Kind Code:
A1
Abstract:
The present application relates to the technical field of batteries, and provides a battery, for use in solving the technical problems of poor safety and poor working stability of a lithium battery in the preparation process of the existing lithium battery. A first conductive member is provided in an accommodation cavity of the battery. An insulating adhesive layer is provided between the first conductive member and a bottom cover. The insulating adhesive layer is connected to the first conductive member and the bottom cover. The bottom cover is provided with a through hole. The first conductive member covers the through hole. An annular side wall is welded to the bottom cover at a side edge close to the bottom cover and a welding mark is formed. A first interval is formed between the welding mark and the insulating adhesive layer. The width of the first interval is more than three times the width of the welding mark. A first tab of a battery core is electrically connected to the first conductive member, and a second tab of the battery core is electrically connected to a housing. According to the present application, the safety of the battery in the preparation process and the working stability of the battery can be improved.
