Abstract

An electrode assembly includes first and second electrode plates respectively comprising first and second active material portions on which first and second active materials are coated and first and second non-coating portions on which the first and second active materials are not coated; a separator interposed between the first and second electrode plates; and first and second electrode tabs respectively coupled to the first and second non-coating portions. In the electrode assembly, portions of the first and second non-coating portions are opposite to each other but the first and second electrode tabs are not opposite to each other in the electrode plates. The electrode assembly is formed by winding the first and second electrode plates from the portion at which the first and second non-coating portions are opposite to each other. A secondary battery includes the electrode assembly and a case accommodating the electrode assembly therein.
