| description | A secondary battery according to one embodiment of the present invention comprises: an electrode assembly which comprises a first electrode, a second electrode, and a separator interposed between the first electrode and the second electrode; a first uncoated tab protruding from the first electrode and a second uncoated tab protruding from the second electrode; and a pouch case which accommodates the electrode assembly, and vertically forms a first bonding unit and a second bonding unit. The first uncoated tab protrudes in the direction of the first bonding unit, and the second uncoated tab protrudes in the direction of the second bonding unit. The first uncoated tab and the second uncoated tab are away from each other by a tab to tab distance. The first uncoated tab may be away by a first distance in one surface of the electrode assembly. The purpose of the present invention is to provide a secondary battery which reduces an area where currents do not flow in the electrode assembly and enables a high rate discharge.
