Title:
GAS EXHAUST MEMBER, BOX, BATTERY, AND ELECTRICAL APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/036524
Kind Code:
A1
Abstract:
The present application relates to the technical field of batteries, and provides a gas exhaust member, a box, a battery, and an electrical apparatus. The gas exhaust member comprises a body part and a one-way flow guide part. The body part is internally provided with a gas exhaust cavity. The body part is provided with a first surface, and the first surface is provided with vent holes communicated with the gas exhaust cavity. The one-way flow guide part is arranged in the body part. The one-way flow guide part is configured to allow emissions discharged by a pressure relief mechanism of a battery cell to enter the gas exhaust cavity through the vent holes, and is configured to prevent discharging of emissions in the gas exhaust cavity through the vent holes. The one-way flow guide part allows emissions to enter the gas exhaust cavity through the vent holes and prevents discharging of the emissions from the gas exhaust cavity, to prevent backflow of the emissions discharged into the gas exhaust cavity by the pressure relief mechanism, so that the risk of dispersion of the emissions inside a battery due to backflow of the emissions in the gas exhaust cavity can be reduced, thereby increasing usage safety of the battery having such gas exhaust member.
