Abstract

This application provides a battery cell, which relates to the technical field of battery cells. The battery cell includes an electrode assembly and a housing, wherein the electrode assembly is arranged in the housing, and an explosion-proof structure is provided on the housing; a valve opening area S of the explosion-proof structure, a valve opening pressure P of the explosion-proof structure, an electrolyte injection amount m of the battery cell, and a capacity C of the battery cell satisfy 2.4 ≤ S×P-C/(m×1000) ≤ 5.4. This application appropriately sets the valve opening area of the explosion-proof structure, valve opening pressure of the of the explosion-proof structure, electrolyte injection amount of the battery cell, and the capacity of the battery cell, so that when the battery cell fails and causes thermal runaway, the explosion-proof structure can work in time, and different parameters, for example the capacity of the battery cell, can be set according to actual conditions, so as to meet the explosion-proof requirements of large-capacity batteries.
