Patent ID: 7803480

Claim:
A prismatic lithium ion battery comprising: a winding shape electrode assembly formed by accumulating and winding two electrodes including electrode taps extended to the upper direction of the winding axis, and a separator preventing a short circuit between the two electrodes; a prismatic can accommodating the electrode assembly; a finishing tape which is attached to at least a part of the outer surface of the winding shape electrode including the winding end of the electrode assemble; and a lower part tape which is attached for enclosing a bottom surface of the electrode assembly and at least a part of the outer surface adjacent to the bottom surface; wherein the finishing tape and the lower part tape are attached to the electrode assembly in the position in which the finishing tape does not overlap the lower part tape; and wherein the finishing tape is installed in the upper ½ range of width in the upper and the lower direction of the outer surface of the electrode assembly.
