Abstract: A battery cell includes: a housing; a cover plate located at an end of the housing; a pole core located in the housing and having an electrode tab electrically connected to a conductive terminal disposed on the cover plate; an inner spacer including a bottom plate disposed on a surface of the pole core facing the cover plate, an end of a connecting plate connected to an edge of the bottom plate and formed in a bent shape with an edge of the bottom plate, and a support plate connected to another end of the connecting plate formed in a bent shape with the support plate and extending from the bottom plate. A part of the electrode tab extends from a surface of the support plate facing the pole core to a surface away from the pole core.
