Research abstract

The program will develop the necessary algorithms and modeling tools needed to assess the useful remaining life in lithium-ion batteries after abnormal operating conditions. The modeling tools will be designed to be implemented into an advanced prognostic and health maintenance system that will actively determine when service of critical components will be needed. The developed model will be based on physical processes that occur during abnormal discharge conditions using porous electrode theory and concentrated solution theory. Existing models of lithium battery performance will be augmented to include the fade mechanisms of interest.
