Title:
HOUSING ASSEMBLY, BATTERY CELL, BATTERY, AND ELECTRICAL APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/077491
Kind Code:
A1
Abstract:
Embodiments of the present application provide a housing assembly, a battery cell, a battery, and an electric apparatus. The housing assembly comprises: a housing member comprising an inner surface and an outer surface which are oppositely provided, and a first through hole running through the inner surface and the outer surface; an insulating member at least partially located on the outer surface of the housing member, and the insulating member comprising a second through hole communicated with the first through hole; electrode terminals mounted in the first through hole and the second through hole so as to be insulated and isolated from the housing member by means of the insulating member; and a flow blocking assembly, the flow blocking assembly being used for blocking a liquid from entering a gap between the housing member and the electrode terminals through a gap between the insulating member and the housing member. According to the housing assembly provided by the technical solution of the present application, the possibility of electronic conduction between the housing member and the electrode terminals due to the presence of a by-product of an electrolyte is effectively reduced, thereby reducing the risk of corrosion and liquid leakage of a housing of a battery cell, and effectively improving the safety performance and quality of the battery cell.
