Recent fire statistics released by the Korean Fire Agency indicate that a total of 678 lithium-ion battery-related fires occurred in South Korea over the past five years (2020–2024). While electric kickboards and electric bicycles account for the majority of these incidents, fires involving electronic cigarettes and disposable electronic cigarettes have continued to occur persistently. As the use of electronic cigarettes becomes more widespread, particularly among adolescents, concerns regarding fire safety are increasing. This study experimentally investigates ignition mechanisms of electronic cigarettes and disposable electronic cigarettes by reproducing three critical failure conditions: overcharging, mechanical compression, and e-liquid leakage combined with moisture infiltration. Controlled experiments were conducted on lithium-ion and lithium-polymer batteries commonly used in e-cigarette devices. Under overcharge conditions without functional protection circuits, thermal runaway occurred within 45–75 seconds, causing battery rupture or explosion. Mechanical compression tests showed that loads exceeding 150 kgf can induce internal short circuits and thermal deformation, suggesting ignition risks during disposal. Prolonged exposure to e-liquid and moisture further degraded protection circuits, resulting in delayed ignition. These results confirm that fires involving electronic cigarettes can originate not only during usage and charging but also during disposal stages, depending on battery failure modes. The findings underscore the need for improved charging safety practices, enhanced protection circuit designs resistant to liquid ingress, and systematic disposal management for battery-containing electronic cigarette products.
