NOVELTY - Rechargeable battery (100) comprises: an electrode assembly (10) comprising a first electrode, a second electrode, and a separator (13) between the first and second electrodes; a case (20) receiving the electrode assembly; a cap plate (30) coupled to the case; an electrode terminal that connects the electrode assembly to an outside of cap plate; and a lead tab electrically connecting the electrode assembly and electrode terminal. The electrode assembly comprises a coated region of the first electrode, and an uncoated region of the first electrode adjacent an end portion of the coated region.    USE - The rechargeable battery is useful in an electric vehicle or a hybrid electric vehicle.    ADVANTAGE - The rechargeable battery: exhibits improved dispersion and emission of an internal gas by providing an exhaust path in communication between the inside and outside of an electrode assembly at an uncoated region of the electrode assembly; has through holes which are formed in the uncoated region to remove a portion of the uncoated region, hence reduces the weight of the electrode assembly and the rechargeable battery; and is prevented from explosion and short circuit.    DETAILED DESCRIPTION - Rechargeable battery (100) comprises: an electrode assembly (10) comprising a first electrode, a second electrode, and a separator (13) between the first and second electrodes; a case (20) receiving the electrode assembly; a cap plate (30) coupled to the case; an electrode terminal that connects the electrode assembly to an outside of the cap plate; and a lead tab electrically connecting the electrode assembly and the electrode terminal. The electrode assembly comprises a coated region of the first electrode, and an uncoated region of the first electrode adjacent an end portion of the coated region, where the uncoated region has a through hole formed in it and connects an inner portion of the electrode assembly to an outside of the electrode assembly.
