Abstract: A battery cell includes: a housing, an electrode assembly, a first insulator, a support assembly, and a second insulator. The housing forms an accommodation cavity. The electrode assembly is accommodated in the accommodation cavity. The electrode assembly includes a first electrode plate, a second electrode plate, and a separator disposed between the first electrode plate and the second electrode plate. The first electrode plate and the second electrode plate are stacked along a first direction. The first insulator includes a first insulation portion. The first insulation portion is disposed on one side of the electrode assembly and parallel to the first direction. The first insulation portion includes a first channel that runs through the first insulation portion.
