Problems solved by technology

However, the explosion-proof valve must not only avoid rupture during transportation and production, but also burst out in time when the air pressure in the battery is too high, which makes the production requirements of the explosion-proof valve higher and the production cost higher

Abstract

The invention discloses a cover plate of a battery and the battery. A cover plate of a battery according to an embodiment of the present invention comprises: a body part; a deformation part; the deformation part is configured to deform in response to temperature increase, so that the cover plate is broken, and an exhaust port is formed; the body part is connected with the peripheral side of the deformation part. According to the battery cover plate provided by the embodiment of the invention, under the condition that the temperature is increased, the deformation part can deform under the combined action of the temperature and the air pressure, so that the cover plate is quickly broken to form the exhaust port, the air pressure in the battery is exhausted from the exhaust port, and the safety of the battery is effectively ensured.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a cover plate of a battery and a battery. Background technique [0002] In order to ensure the safety of the battery, an explosion-proof valve is generally set on the battery, so that when the temperature in the battery rises and the air pressure increases, the explosion-proof valve bursts in time to release the pressure. However, the explosion-proof valve not only needs to avoid rupture during transportation and production, but also bursts in time when the air pressure in the battery is too high, which makes the production requirements of the explosion-proof valve higher and the production cost higher. SUMMARY OF THE INVENTION [0003] Embodiments of the present invention provide a cover plate for a battery and a battery. [0004] The cover plate of the battery according to the embodiment of the present invention includes: [0005] body part; [0006] deformation part; ...
