Abstract
Provided is a superwide pouch type secondary battery comprising an electrode assembly including a cathode plate, an anode plate, and a separator; a pouch surrounding the electrode assembly; and electrode tabs connected to both ends of the electrode assembly and protruding outward of the pouch, wherein the electrode tabs connected to the both ends of the electrode assembly include one or more cathode tabs and anode tabs, respectively, and width of battery cell is more than 4 times longer than height of battery cell such that loading efficiency of the pouch type secondary battery into a vehicle and an energy density may be improved without increasing an internal electrode.
