SECONDARY BATTERY

摘要

PURPOSE: A secondary battery is provided to prevent the lowering of a sealing force of a sealing part generated when an electrode tab is drawn from a case and to increase inner capacity of a battery by excluding a space required for coupling an electrode tab. CONSTITUTION: A secondary battery(100) comprises: an electrode assembly including a plurality of first and second electrode plates and a separator interposed between the first and second electrode plates; a first electrode tab included in the first electrode plate and a second electrode tab included in the second electrode plate; a case(140) in which the first and second electrode tabs are accommodated thereinside together with the electrode assembly; and first and second external lead terminals(150,160) which are electrically connected to the first and second electrode tabs.
