摘要
PURPOSE: An electrode assembly is provided to minimize the tear of a separation film even if strong tensile force is applied, thereby effectively preventing the internal short. CONSTITUTION: An electrode assembly is such that two or more unit cells containing a monoaxially oriented separation film are folded with a long sheet-like monoaxially oriented separation film, wherein the monoaxially oriented separation film of the unit cell and the long sheet-like monoaxially oriented separation film are crossed at right angles in an oriented direction of the separation film.
