Abstract
(EN)
The present invention relates to a secondary battery. The secondary battery according to the present invention comprises: an electrode assembly wherein a first electrode, a separator, and a second electrode are alternately stacked and wound; a can forming an accommodating portion to accommodate the electrode assembly therein, and including a first can and a second can, each formed in a cylindrical shape opened in a mutually facing direction; and an insulating body insulating an overlapped portion between the first can and the second can, wherein the first can is in direct contact with an end of the first electrode to form a first electrode terminal, and the second can is in direct contact with an end of the second electrode to form a second electrode terminal.
