The disclosure provides a battery, a battery module, a battery pack, and a battery manufacturing method. The battery includes a housing, a cell, and a pole column subassembly. The housing includes two first surfaces opposite to each other in a first direction. The cell is arranged in the housing. The cell includes a cell body and a tab portion. The tab portion includes two or more single-piece tabs extending from the lateral side of the cell body. When the single-piece tabs are flattened along the direction perpendicular to the lateral side of the cell body, the overlapping direction of the single-piece tabs is the first direction. The pole column subassembly is arranged on a first surface and connected with the tab portion. The orthographic projections of the tab portion and the pole column subassembly along the first direction are at least partially overlapped on a first surface.

A battery, a battery module, and a battery pack are provided. The battery includes a cell and a casing. The casing accommodates the cell. The cell includes a cell body, a first insulating film and a second insulating film. The first insulating film is disposed on a surface of the cell body and covers a part of the surface of the cell body. The second insulating film is disposed to be independent from the first insulating film and is partially adhered to a surface of the first insulating film away from the cell body, and is partially adhered to the surface of the cell body that is not covered by the first insulation film. The first insulating film is fixed firmly to the cell body.
The disclosure discloses a battery and a battery apparatus. The battery includes two opposite first surfaces and four second surfaces disposed around the first surfaces, a pole assembly and a busbar. An area of the first surface is larger than an area of the second surface. The pole assembly is disposed on the first surface. The busbar is bent into a first segment and a second segment. The first segment is located at a side of the first surface where the pole assembly is disposed and is connected to the pole assembly. The second segment is parallel to or substantially parallel to a second surface and is used for electrically connecting the pole assembly of another battery.
