The primary cause of vape explosions is related to the lithium-ion batteries powering these devices. These batteries are sensitive to physical damage, overcharging, overheating, or manufacturing defects. When any of these issues occur, it may lead to thermal runways, a process where the battery's temperature rapidly escalates, potentially causing swelling, rupture, or fire. Other contributing factors include using unapproved or incompatible chargers, carrying batteries in pockets with metal objects, or physically damaging the device. Furthermore, substandard or counterfeit devices often lack proper safety mechanisms, elevating risks substantially.
