Abstract
(EN)
The invention provides a secondary battery and a battery module. The secondary battery comprises an electrode assembly, a housing, and a top cover assembly. The housing is provided with a receiving chamber, and the electrode assembly is received in the receiving chamber. The electrode assembly comprises a plurality of electrode units, which are stacked in the axial direction of the receiving chamber. The top cover assembly comprises a top cover plate and an insulating member disposed on the inner side of the top cover plate. The top cover plate is connected to the housing, and the insulating member is located on one side of the electrode assembly in the axial direction. A first surface is provided on the side of the insulating member close to the electrode assembly, and the first surface is flat. The battery module comprises secondary batteries; a plurality of secondary batteries are provided and arranged in sequence, and the arrangement direction of the plurality of secondary batteries is perpendicular to the axial direction.
