Abstract: The embodiments of this application provide a battery cell, a battery, a power consumption device, and a battery cell manufacturing method and device, which pertain to the technical field of batteries. The battery cell includes a housing, an electrode assembly, an end cover, and a current collecting member. The housing has an opening. The electrode assembly is accommodated in the housing. The end cover covers the opening and is connected to the housing in a sealed manner. The current collecting member is accommodated in the housing and is located on a side of the electrode assembly facing the end cover, and the current collecting member is configured to be connected to the housing and the electrode assembly, so that the electrode assembly is electrically connected to the housing.

Abstract: A battery cell includes a casing provided with openings at two ends of the casing in a first direction, a first end cap and a second end cap connected to the casing and configured to close the openings at the two ends of the casing, respectively, and a connecting piece disposed in the casing and configured to be connected to the first end cap or be connected to the first end cap and the second end cap. The battery cell is provided with a weak structure at one of the two ends. A connecting force between the connecting piece and the first end cap is greater than a connecting force between the connecting piece and the second end cap. A connecting position where the connecting piece is connected to the first end cap is located in an area surrounded by the weak structure.

Abstract: Embodiments of the application provide a battery cell, a manufacturing method and a manufacturing system therefor, a battery and an electric device. According to the embodiments of the application, the battery cell includes: an electrode assembly including a first electrode piece; a housing, configured to accommodate the electrode assembly and including an electrode lead-out portion; an adapter, configured to electrically connect the electrode lead-out portion and the first electrode piece.
