Lithium-ion batteries(LIB) have many advantages and are widely used as power devices for smartphones, electric vehicles and are becoming an essential element in modern society. As the usage of LIB increases, the number of batteries that are discarded after use increases, which leads to a fire. LIB fires are usually caused by overcharging, but in the case of LIB waste, environmental factors dominate. Therefore, as a result of confirming the explosion risk of LIB according to changes in temperature, humidity, and SOC(state of charge) in this study, it was concluded that the LIB waste has a higher rate of temperature increase in a high-humidity environment than in a low-humidity environment. Therefore, in a high-temperature and high-humidity environment, the time to reach thermal runaway of the LIB waste is shortened, and thus the LIB waste is exposed to the of explosion more quickly.
