This thesis extends the full-scale electrochemical model for a Lithium-ion battery based on the porous electrode theory to incorporate aging mechanisms of solid electrolyte interface formation, cyclic electrode degradation, and lithium plating during overcharge, automotive vibrations, mechanical stress, and cell temperature, as reported in the existing literature. Further, the thesis presents the scope of the parameters used in the model to enable designers to extend the equations for new mechanisms and variability of other parameters.
An increased set of equations makes the complexity of the model even higher, and it would be very computationally complex to simulate this model. This makes this model unsuitable for inexpensive processors of mobile applications like an automotive battery management system while increasing the uncertainty faced by PDE solvers. However, as the physical models get close to an actual lithium-ion battery behavior, they could accelerate its development, shortening the design life of batteries.
