FOLDABLE POUCH-SHAPED BATTERY CELL AND METHOD OF MANUFACTURING THE SAME

The present invention relates to a pouch-shaped battery cell having an electrode assembly received in a pouch-shaped battery case, wherein the electrode assembly includes positive electrodes and negative electrodes, each of the positive electrodes and the negative electrodes having a structure in which the length of the electrode in an overall width direction is less than the length of the electrode in an overall length direction, each of the positive electrodes and the negative electrodes has an uncoated portion, which is a portion coated with no electrode mixture, formed parallel to outer peripheries of the electrode in the overall width direction or outer peripheries of the electrode in the overall length direction and a coated portion, which is coated with an electrode mixture, formed at the remaining portion of the electrode excluding the uncoated portion, and a stepped structure is formed at the part of the pouch-shaped battery case corresponding to the uncoated portion so as to be recessed inwards.
