Abstract:
1. A battery, comprising: an electrode assembly having an electrode uncoated region, including a plurality of electrode uncoated regions; a current collector including a current collector coupling part coupled to the electrode uncoated region, the current collector coupling part includes a plurality of current collector coupling parts coupled to the plurality of electrode uncoated regions; a case accommodating the electrode assembly; and an elastic damping member, the elastic damping member engaging the current collector coupling part, being disposed between a pair of current collector coupling parts, and including a first region coupled to at least one of the electrode uncoated regions, a second region pressing against the pair of the current collector coupling parts, and a third region contacting an inner side of the case, wherein, in an assembled condition of the electrode assembly and the case, the elastic damping member is in a compressed state to exert a pressing force that presses the pair of current collector coupling parts.
