Effects of Temperature on Mechanical Response of Lithium ion Batteries to External Abusive Loads 2019-01-1002
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 degree to +50 degree centigrade. Therefore, characterization of response under varying temperature is of utmost importance. We have tested battery cells at a range of temperatures and have documented the changes under crush and indentation. Our results show that extreme hot or cold temperatures can have a significant effect on the mechanical properties of lithium ion batteries.
