  "textContent": "Disclosed herein is a pouch-shaped secondary battery in which a unit cell, including an electrode assembly having a positive electrode and a negative electrode stacked with a separator interposed therebetween, electrode tabs, and electrode leads, is mounted in a pouch-shaped case, wherein the pouch-shaped secondary battery includes a unidirectional structure through which electrode leads oriented in two opposite directions are connected to electrode terminals oriented in a single 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 lifespan of a unidirectional cell is reduced due to heat generated from electrode leads and due to nonuniform use of active materials in the cell at the time of charging and discharging the cell. The disclosed pouch-shaped secondary battery has the effect of solving the above problems.",
