Lithium battery pack deformation battery classification

Do lithium-ion batteries have thermal and electrochemical behavior under large mechanical deformation?

A simultaneously coupled modeling approach to study the electrochemical and thermal behavior of lithium-ion batteries under large mechanical deformation has been developed. The thermo-electrochemical pseudo-2D (P2D) battery model is coupled with a mechanical material model.

What are lithium-ion batteries?

Lithium-ion batteries (LIBs) are currently the primary energy storage devices for modern electric vehicles (EVs). Early-cycle lifetime/quality classification of LIBs is a promising technology for many EV-related applications, such as fast-charging optimization design, production evaluation, battery pack design, second-life recycling, etc.

How does mechanical stress affect lithium-ion batteries?

Provided by the Springer Nature SharedIt content-sharing initiative Mechanical stress during the cycling process notably impacts the performance of lithium-ion batteries (LIBs), making it crucial to accurately monitor stress generation and propagation during battery operation.

Why do we use a pseudo-2d physics model for lithium-ion batteries?

Electrochemical model (pseudo two-dimensional model) The physics-based nature of the model gives great insights into understanding each phenomenon going on in the battery. In this work, we choose pseudo-2D model [13, 21, 22] to capture the detailed physics in each components of batteries, for design and analysis of lithium-ion batteries.
