Abstract: An electrode assembly, in which a positive electrode, a separator, and a negative electrode are repeatedly stacked includes a shrinkage film made of a material having a thermal shrinkage rate greater than that of the separator, the shrinkage film being shrunk in area at a specific temperature or more, wherein the shrinkage film is disposed instead of the separator at one or more positions between the positive electrode and the negative electrode so that, when the shrinkage film is shrunk by an increase of a temperature, the positive electrode and the negative electrode, which are adjacent to each other with the shrinkage film therebetween, partially contact each other to generate microcurrent.
