Thermal destruction experimentation methods

This section aims to present briefly the experimental methods used to evaluate the performance of ceramics and CMCs under conditions of thermal shock. Reference is made to techniques used to impose the actual thermal shock condition as well as the destructive and non-destructive methods employed to assess damage morphologies and changes in residual properties. 

The safety of the system is analytically determined from the joint contributions of all components. Modeling of thermal and mechanical properties of batteries remains a useful method to approximate their systemic behavior. However, the experimental verification and the (expensive) destructive testing still provide the most valuable data on the actual event progress and propagation. Improvements in the accuracy of thermal models as well as the ever-increasing wealth of data from the past and ongoing testing are expected to improve the reliability of the cell performance predictions.
