Provided are a top cover assembly of a cell, a cell, and a power battery. The top cover assembly includes an insulation cover plate, a metallic support plate, a terminal assembly, and an elastic seal. The metallic support plate and the insulation cover plate are stacked in a thickness direction. The terminal assembly passes through the insulation cover plate and the metallic support plate in the thickness direction to connect the insulation cover plate and the metallic support plate. The elastic seal surrounds a peripheral outside of the metallic support plate and the insulation cover plate. The elastic seal has a positioning flange provided on an inner peripheral surface thereof and is configured to be in a sealing fit with a housing of the cell. The positioning flange is sandwiched between the metallic support plate and the insulation cover plate.

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 relates to a technical field of batteries, and a battery and a battery apparatus are provided. The battery includes a cell, and the cell includes a cell body and tab portions. Each of the tab portions extends from one side of the cell body. The battery further includes a housing. The housing is a hollow structure, and the hollow structure is formed inside the housing. The cell is disposed in the housing, and the housing includes a first surface and a second surface opposite to each other. The first surface is provided with liquid injecting holes, and the liquid injecting holes penetrate the first surface and do not penetrate the second surface. An orthographic projection of the cell body on the first surface does not overlap the liquid injecting holes.

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.
