Title:
BATTERY AND ELECTRIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/077604
Kind Code:
A1
Abstract:
Embodiments of the present application provide a battery and an electric apparatus, capable of enhancing the safety performance of the battery. A battery (10) comprises: a plurality of battery cells (20), wherein at least one battery cell (20) is provided with a first pressure relief mechanism (213); a box body (110), being provided with a second pressure relief mechanism (113); and an enclosure mechanism (30), used for defining a first gas discharging space (310) corresponding to the first pressure relief mechanism (213) of the at least one battery cell (20), and provided with an opening (301) communicated with the first gas discharging space (310). When the first pressure relief mechanism (213) is actuated, an emission of the at least one battery cell (20) enters the first gas discharging space (310) from the first pressure relief mechanism (213) and is discharged to the second pressure relief mechanism (113) via the opening (301), and the minimum length of the discharging path of the emission between the first pressure relief mechanism (213) and the second pressure relief mechanism (113) is greater than the shortest distance between the first pressure relief mechanism (213) and the second pressure relief mechanism (113).
