US 2010/0304198 A1 · ELECTRODE ASSEMBLY FOR SECONDARY BATTERY AND METHOD OF MANUFACTURING THE SAME

Abstract

An electrode assembly for a secondary battery and a method of manufacturing the same are disclosed. The electrode assembly includes a first separator wound to form a plurality of stacked first separator members; a second separator wound with the first separator to form a plurality of stacked second separator members to be respectively positioned between the first separator members; and a plurality of electrode members positioned between the first separator members and the second separator members. An inner surface of one of the first separator members positioned at the innermost side and an inner surface of one of the second separator members positioned at the innermost side face each other.
