Abstract
(EN)
In order to solve the problems, a pouch-type secondary battery according to an embodiment of the present invention comprises: an electrode assembly having electrodes and a separator stacked therein, the electrodes including a cathode and an anode; a pouch-type battery case receiving the electrode assembly; an electrode tab connected to the electrodes and protruding from one side of the electrode assembly; a first electrode lead connected to the electrode tab at one end thereof; a second electrode lead, one end of which is connected to the other end of the first electrode lead and the other end of which protrudes to the outside of the battery case; and a connection part connecting the first electrode lead to the second electrode lead by attachment therebetween, wherein a first sloping surface is formed on at least one of the other end of the first electrode lead and the one end of the second electrode lead.
