Document Type and Number:
WIPO Patent Application WO/2023/226164
Kind Code:
A1
Abstract:
The present application provides a housing for a battery cell, the battery cell, a battery, and an electric device. An accommodating cavity for accommodating an electrolyte is formed in the housing for the battery cell; the housing comprises a gas extraction mechanism, and gas in the accommodating cavity can be extracted out by means of the gas extraction mechanism; the gas extraction mechanism comprises: a gas extraction hole, which is provided on the housing; and an electrolyte blocking structure working in conjunction with the gas extraction hole and provided in the accommodating cavity, the electrolyte blocking structure being configured to block the electrolyte from being extracted out from the gas extraction hole. The electrolyte blocking structure comprises: a first body which is of a hollow structure; and an electrolyte blocking portion which is provided in the first body. In the solution of embodiments of the present application, the electrolyte blocking structure can block the electrolyte from being extracted out when gas is extracted from the interior of the housing, so that an electrolyte loss is reduced, and the battery performance is improved.
