Electrode assembly for secondary battery and method for fabricating the same

摘要

A roll electrode assembly of a secondary battery includes a positive electrode rolled having a plurality of turns, a negative electrode rolled having a plurality of turns, and first and second separators each rolled to have a plurality of turns. Each turn of the first separator is disposed between each outer surface of the turns of the negative electrode and each inner surface of the turns of the positive electrode. Each turn of the second separator is disposed between each outer surface of the turns of the positive electrode and each inner surface of the turns of the negative electrode. The thickness of the second separator is thinner than that of the first separator.
