Customer ServiceFor experiments conducted the self-heating profiles due to chemical reactions in the interior of a Li-ion cell under adiabatic environment,adiabatic calorimetry studies were ideal for battery safety testing in order to determine the effects of thermal runaway and thermophysical parameters.
As seen from the adiabatic calorimetry tests, the cell components expanded and tore apart the stainless steel container during thermal runaway, and the reaction provided sufficient energy to create a pressure wave. Overheating and exposure to a certain critical temperature may causedegradation, fracturing, and failure of a battery pack , .
Any heat, even small amounts of heat, cause the temperature to rise and accelerates the reaction producing even more heat. This is the adiabatic condition and it is this precise condition that adiabatic calorimeters can safely measure in the small scale. It is this same condition that can be found inside large processing vessels as well as inside
A cell can be regarded as a reaction system in which heat is generated by the reactions among the cell components, and the measured adiabatic calorimetry data were used in thermal explosion energy calculations tomap the battery potential.
Therefore, adiabatic calorimeters are generally designed to be much more robust than many other types of calorimeters. When looking at a thermal runaway as a part of a chemical process in a reactor, the reaction produces heat which increases the temperature of the reaction mixture and further increases the rate of reaction.
When the potential exists for an adiabatic runaway reaction, the temperature and the pressure trajectories of the reaction can be used as a proper measure of the magnitude of the thermal hazard of the Li-ion battery using the VSP2 adiabatic calorimetric methodology.
