BATTERY CELL, BATTERY,POWER CONSUMPTION DEVICE

Embodiments of the present disclosure provide a battery cell, a battery, a power consumption device, and a device and a method for manufacturing a battery cell. The battery cell comprises an electrode assembly, a housing, an end cover, and a first insulation member. The electrode assembly comprises a first tab. The housing is configured to accommodate the electrode assembly, the housing has an opening, and a first limiting portion is formed on an inner circumferential wall of the housing. The end cover is configured to cover the opening, and in a thickness direction of the end cover, the first limiting portion is configured to limit movement of the end cover in a direction towards the electrode assembly. The first insulation member is at least partially provided between the first tab and the first limiting portion, so as to insulate and isolate the first tab from the first limiting portion. The first insulation member insulates and isolates the first tab and the first limiting portion, thus reducing the risk of safety problem caused by short circuit inside the battery cell due to electrical connection formed between the first tab and the first limiting portion caused by contact of the first tab with the first limiting portion as the first tab becomes loose towards the end cover.
