UL9450A Lithium Battery Thermal Runaway Combustion and Explosion Experimental Chamber

The UL9450A Lithium Battery Thermal Runaway Combustion and Explosion Experimental Chamber is specifically designed for conducting thermal runaway combustion and explosion experiments on lithium batteries. This specialized equipment addresses the critical safety challenges posed by lithium battery failures, including rapid explosion, instantaneous energy release, and emission of toxic gases.

Lithium battery combustion and explosion experiment chamber is engineered for thermal runaway testing where batteries can explode rapidly, releasing massive energy instantly along with various toxic and harmful gases. The pressure-resistant tank is designed to withstand explosion shock pressurization processes.

While actual explosion energy varies with battery quantity and capacity, the test chamber is designed and manufactured for impact pressure capacity of 1MPa. Shock pressure characteristics include instantaneous pressure increase followed by rapid return to normal or slightly elevated pressure levels.
