Pressure Vessel for Battery Abuse Test If thermal runaway occurs in a lithium battery, the battery material will undergo a series of chemical reactions, generating a large amount of heat and flammable and toxic gases, resulting in the explosion of the battery due to a rapid increase in internal temperature and pressure, followed by the leakage of flammable gases, which will cause violent combustion when encountering external air at high temperatures, forming a jet fire or an explosive fireball, thus causing the loss of control of other surrounding monomers and triggering safety accidents. This can lead to a safety accident. The charge state, service time, and material system of the battery can all lead to changes in the composition of the gas produced by the battery, which can affect its combustion and explosion characteristics and the risk of thermal runaway. The Pressure Vessel for Battery Abuse Test provides a safe container in which the tested cells can be thermally runaway in a reproducible way while analyzing the conditions of thermal runaway and the changes in temperature and pressure during the thermal runaway process. The Pressure Vessel consists of an explosion-resistant pressure vessel, a thermal runaway trigger system, a temperature measurement system, and a pressure measurement system, which can trigger thermal runaway of lithium-ion batteries by heating, short-circuiting, overcharging, and over-discharging in the vessel.
