<p>PURPOSE: A secondary battery is provided to improve impregnation rate of electrolyte, to increase heat-emitting effect, and to lower the change of a shape, by forming a separation space between finish tapes. CONSTITUTION: A secondary battery(100) comprises: an electrode assembly(110) that is wound by successively laminating a first electrode plate, a separator and a second electrode plate; and a plurality of finish tapes(121,122,124) attached at the outer surface(117) of the electrode assembly. The finish tapes are separated from each other along a wound direction of the electrode assembly.</p> |
