    Abstract: A cell, a battery pack, and an electric vehicle are provided in the present disclosure. The cell includes a hermetical metal housing and at least two hermetical accommodating cavities, multiple electrode core assemblies, and an encapsulation film arranged in the metal housing. The electrode core assemblies are arranged along a first direction. The electrode core assemblies are connected in series. A length of each electrode core assembly extends along the first direction. The electrode core assembly includes an electrode core assembly body and a first electrode and a second electrode configured to lead out a current. The first electrode and the second electrode are respectively arranged on two sides of the electrode core assembly body along the first direction. At least one of the accommodating cavities is defined by the encapsulation film, and the electrode core assembly body is arranged in the accommodating cavity. A length of the cell extends along the first direction. The length of the cell ranges from 400 mm to 2500 mm. A thickness of the cell extends along a second direction perpendicular to the first direction. A ratio of the length to the thickness of the cell ranges from 5 to 250.

    Abstract: A battery pack and an electric vehicle are provided. The battery pack includes a cell array and two first reinforcing plates. The cell array includes a number of cells. Each of the cells is defined with a length L, a thickness D, and a height H between the length L and the thickness D. The number of cells are arranged along a thickness direction, and the cells are adhered to each other by a structural adhesive. The two first reinforcing plates are arranged opposite to each other and are respectively adhered to two surfaces of the cell array along the arrangement direction of the cells, and are configured to constrain relative positions between the cells.
