Title:
TOP COVER ASSEMBLY, BATTERY CELL, BATTERY AND ELECTRIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/016451
Kind Code:
A1
Abstract:
The present application relates to the technical field of batteries. Particularly disclosed are a top cover assembly, a battery cell, a battery and an electric device. The top cover assembly provided by the present application comprises a top cover sheet, an electrode terminal, an adapter sheet, a current collecting disc and a buffer member, wherein the electrode terminal is arranged on the top cover sheet in a penetrating manner; the adapter sheet is connected to the electrode terminal; the current collecting disc is connected to the adapter sheet; a first bending portion is formed at the joint between the current collecting disc and the adapter sheet; the buffer member is connected to the adapter sheet and/or the current collecting disc; and when the first bending portion is in a bending state, the buffer member is arranged between the adapter sheet and the current collecting disc, and the two ends of the buffer member respectively abut against the adapter sheet and the current collecting disc. In the technical solution of the present application, a buffer force can be provided for the adapter sheet in a vibration direction, so that the vibration amplitude of the adapter sheet relative to the current collecting disc is reduced, thus reducing a pressing force on the first bending portion, preventing the first bending portion from a fracture under long-term vibration pressing, and ensuring the safety and reliability of use of the battery.
