    • A secondary battery is provided to discharge charged electricity through an application of an electric current between electrode terminals when temperature of the battery is increased by abnormal operation of the battery, thereby improving battery safety. A secondary battery(500) has an electrode assembly of an anode/separator/cathode structure impregnated with an electrolytic solution, which is contained in a case. A positive electrode terminal(510) and a negative electrode terminal(520) of the electrode assembly are formed on the outside of the case so as to be connected to a predetermined external circuit. A connecting member(100) is electrically connected to the electrode terminals, wherein the connecting member cuts off electricity in a normal operating state and turns on an electric current at high temperature of abnormal operating state.
