Abstract
Disclosed herein is a pouch-shaped secondary battery configured to have a structure in which a unit cell, including an electrode assembly constituted by a positive electrode and a negative electrode, stacked in the state in which a separator is interposed between the positive electrode and the negative electrode, electrode tabs, and electrode leads, or a cell assembly, including two or more stacked unit cells, is mounted in a pouch-shaped case, wherein the pouch-shaped secondary battery includes a unidirectional structure in which electrode terminals oriented in two directions are changed to electrode terminals oriented in one direction. In the case in which a battery pack is constituted using a bidirectional cell, a large space is required, whereby the energy density of the battery pack is reduced. The disclosed pouch-shaped secondary battery has the effect of solving the above problem.
