Abstract

Provided is an electrochemical cell having an improved structure to increase the connection strength between a terminal and current collectors, decrease the electric resistance of a connection part between the terminal and the current collectors, and improve the uniformity and reliability of the connection part. The electrochemical cell includes: an electrode including a current collector and an active material layer disposed on a part of the current collector, wherein an edge portion of an extension part of the current collector configured to be connected to a terminal is thicker than the part of the current collector on which the active material layer is disposed; an electrode assembly including at least the electrode as one polarity electrode and in which current collector extension parts of positive and negative electrodes are arranged to face opposite sides; and a terminal connected to a side surface of the electrode assembly, wherein the terminal is connected to the side surface of the electrode assembly by using at least one of welding, a conductive adhesive, and soldering.
