In this study, the explosion processes of the battery according to by heating was identified using complex sensors including temperature, infrared (IR), visible, and ultraviolet (UV) sensors. A safe chamber was prepared for the explosion of the batteries according to heating. In order to detect signals from the battery during heating, complex sensors including temperature, IR, visible, and UV sensors were used inside the safe chamber. The heating was increased from room temperature to 165℃ at 10℃/min and then, kept 165℃. During the heating was kept at 165℃, the battery was exploded and a temperature was increased up to 380℃ abruptly due to explosion of the battery. Before the battery was exploded, the signals of the sensors were not detected. However, during explosion of the battery, the signals of IR, visible, and UV sensors were strongly detected. By analyzing various signals of the these sensors, the explosion of the battery according to heating was investigated.
