Document Type and Number:
WIPO Patent Application WO/2023/283808
Kind Code:
A1
Abstract:
The present application discloses a battery cell, a battery, and an electronic apparatus. The battery cell comprises: a housing the interior of which is filled with an electrolyte; at least one core component disposed in the housing; and at least one closed liquid capsule that contains an electrolyte, the liquid capsule being disposed in the housing, and being arranged at least corresponding to a sidewall of the sore component. At least one weak structure is disposed on the liquid capsule, and when the pressure in the liquid capsule reaches a threshold, the electrolyte in the liquid capsule breaks through the weak structure and flows out of the liquid capsule. In the battery cell of embodiments of the present application, by disposing in the housing the liquid capsule having the weak structure and enabling the liquid capsule to be arranged corresponding to the sidewall of the core component, the deterioration of battery performance caused by lithium precipitation or local electrolyte depletion in a battery can be alleviated when the core component expands during use.
