Abstract: A battery including a housing assembly, an electrode assembly, and a conductive assembly. The housing assembly includes a first housing fixed on a second housing. The second housing is provided with a cavity and includes a bottom plate. The electrode assembly is disposed in the cavity. The bottom plate contains an elastic portion protruding toward the first housing. The electrode assembly includes a first electrode plate and a second electrode plate stacked together. A surface of the first electrode plate facing back from a center of the electrode assembly contains a first blank foil region uncoated with a first active material and electrically connected to the conductive assembly. A surface of the second electrode plate facing back from the center of the electrode assembly contains a second blank foil region uncoated with a second active material. The elastic portion is electrically connected to the second blank foil region.
