Abstract: Disclosed herein are a secondary battery configured to be prevented from catching fire or exploding in a critical situation such as overcharging and a method of preventing the secondary battery from catching fire or exploding. Since a separator including a low melting point material is used, a short circuit in the battery occurs when the battery is abnormally heated, and the resistance of an electrode is increased when the temperature of the battery increases to a predetermined temperature or higher. As a result, a positive temperature coefficient (PTC) material is operated at a stable State of Charge (SoC). Consequently, it is possible to prevent the occurrence of a thermal runaway phenomenon of the battery.
