Document Type and Number:
Japanese Patent JP7492007
Kind Code:
B2
Abstract:
Embodiments of the present application provide a battery, a power consumption apparatus, and a method and apparatus for producing a battery. The battery (100) includes: a battery cell (20), provided with a pressure relief mechanism (213), the pressure relief mechanism (213) being configured to be actuated when an internal pressure or temperature of the battery cell (20) reaches a threshold, to relieve the internal pressure; a bus component (12), configured to be electrically connected to the battery cell (20); an electrical cavity (11a), configured to accommodate the battery cell (20) and the bus component (12); a collecting cavity (11b), configured to collect emissions from the battery cell (20) when the pressure relief mechanism (213) is actuated; and a sealing structure (215), disposed in an airflow path formed between the pressure relief mechanism (213) and a wall of the electrical cavity (1 1a) and configured to prevent the emissions from reaching the bus component (12) when the pressure relief mechanism (213) is actuated. The battery, the power consumption apparatus, and the method and apparatus for producing the battery according to the embodiments of the present application can enhance safety of the battery.
