ELECTRODE ASSEMBLY FOR SECONDARY BATTERY AND METHOD OF MANUFACTURING THE SAME
First Claim
1. An electrode assembly for a battery comprising:
- a plurality of first electrodes;
a plurality of second electrodes wherein the plurality of first electrodes and the plurality of second electrodes are arranged into an alternating stack of electrodes;
a first separator that is wound through the alternating stack of electrodes so that the first separator is interposed between adjacent first and second electrodes; and
a second separator that is wound through the stack of electrodes so that the second separator is interposed between adjacent second and first electrodes and so that the second separator is interposed between adjacent portions of the first separator that are interposed between the adjacent first and second electrodes.

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.
