Abstract
A battery including an electrode assembly is provided. The electrode assembly has first and second current collectors facing region disposed at a winding start end and at a winding terminal end, respectively. A positive electrode current collector exposed portion and a negative electrode current collector exposed portion face each other through the separator in each of the first and second current collector facing regions. At least one of the positive or negative electrode current collector exposed portion has a first insulating member formed thereon in the first current collector facing region at the winding start end and has a second insulating member formed thereon in the second current collector facing region at the winding terminal end. The second insulating member has a melting point lower than that of the first insulating member.
