Abstract: A method for evaluating an internal short, of the present invention, inserts ionic polymer-metal composites (IPMC) in a battery cell, and applies a voltage to an external conducting wire electrically connected to the IPMC, so as to induce an internal short by means of flexural deformation of the IPMC, thereby evaluating whether the internal short occurs. The method for evaluating an internal short, according to the present invention, inserts and positions, in a battery, the IPMC capable of operating even at room temperature and low voltages and adjusts the voltage, thereby having an advantage of enabling a short to occur at a desired position and area and for a desired period of time.
