Effects of Temperature on Mechanical Response of Lithium Ion Batteries to External Abusive Loads

This paper focuses on mechanical properties of lithium ion batteries subjected to mechanical loading. Researchers have studied mechanical properties of batteries under room temperature. However, the operating temperature for these cells can change from -20 to +60 degrees Celsius. Therefore, characterization of cell’s response under varying temperature is of utmost importance. We have tested battery components and cells at a range of temperatures and have documented the changes in mechanical properties. Our results show that extreme hot or cold temperatures can have a significant effect on the mechanical response of lithium ion batteries under crush and indentation.
