Abstract
(EN)
The present invention relates to a pouch-type secondary battery comprising: an electrode assembly having a structure in which a separator is interposed between a cathode and an anode; and a battery case including a first groove portion for accommodating the electrode assembly and a second groove portion for accommodating a supplementary electrolyte, wherein the second groove portion is positioned on at least one side of the first groove portion, and a sealing line for preventing the movement of the electrolyte accommodated in the second groove portion is formed between the first groove portion and the second groove portion.
