BATTERY CELL, BATTERY, POWER CONSUMPTION APPARATUS, METHOD AND APPARATUS FOR PRODUCING BATTERY CELL

Disclosed is a battery cell, a battery, a power consumption apparatus and a method and an apparatus for producing a battery cell. The battery cell includes: a housing, with a first opening; an electrode assembly, arranged in the housing; an end cover assembly, including an end cover, a pressure relief mechanism and a first insulating member, the end cover covers the first opening, the pressure relief mechanism is arranged on the end cover, the pressure relief mechanism is configured, when an internal pressure or temperature of the battery cell reaches a threshold, to be actuated, the first insulating member is located on a side of the end cover close to the electrode assembly to isolate the electrode assembly and the end cover, and the first insulating member is configured that a projection on the end cover along a thickness direction of the end cover covers the pressure relief mechanism.
