210 may be formed to entirely mold the battery cell 100 except for the exposed ends of the positive electrode tap 114 and the negative electrode tap 115 but the present invention is not limited to any one injection molded structure at this time for coupling between the mounting frame 210 and the top case 220 at least a part of the upper end portion of the battery cell 100 corresponding to the exposed ends of the positive electrode tap 114 and the negative electrode tap 115 may be injection molded a label 230 may be disposed between the outer surface of the battery cell 100 and the mounting frame 210 the label 230 is adhered to a front surface or a rear surface of the battery cell 100 by using a double sided tape or an adhesive solvent the label 230 may preferably be adhered to the outer surface of the battery cell 100 before the mounting frame 210 is disposed on the battery cell 100 the label 230 is adhered to the outer surface of the battery cell 100 in order to display information about the battery cell 100 a protection circuit module 240 is disposed in a cavity 12 formed.
