Title:
BATTERY CELL, BATTERY, AND POWER-CONSUMING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/283807
Kind Code:
A1
Abstract:
The present application discloses a battery cell (1000), the battery cell (1000) comprising a housing (100), at least one cell core (200), and a buffer member (300); the at least one cell core (200) is accommodated in the housing (100); the buffer member (300) is disposed corresponding to a side wall of a cell core (100), the buffer member (300) has an accommodating cavity (305), the outer periphery of the accommodating cavity (305) comprises at least one encapsulation structure (3010), and the encapsulation structure (3010) comprises at least one encapsulation region having a predetermined length; when the pressure in the accommodating cavity (305) exceeds the encapsulation strength of the encapsulation structure (3010), the encapsulation region opens and forms a buffer space communicated with the accommodating cavity (305), thereby reducing the effects of cell core expansion.
