AI Technical Summary
Existing lithium battery combustion testing devices are unable to simulate the dynamic heat release process under real thermal runaway scenarios, and the spray extinguishing method generates corrosive wastewater, affecting the equipment's lifespan and safety.
A lithium battery combustion experimental device was designed. An oxygen delivery component was used to simulate the oxygen environment under actual thermal runaway scenarios, and a nitrogen delivery component was used to quickly extinguish the flame to avoid the generation of corrosive wastewater. A detection module was used to monitor the combustion characteristics in real time.
It improves the accuracy of combustion testing and the safety of the equipment, extends its service life, and avoids the generation of corrosive wastewater.
