Li-ion batteries are the most promising technology for use in electric vehicles in the near future, and as such it is critical to understand their performance at both beginning of life (BOL) and end of life (EOL). In this work different thermal and capacity fade effects (e.g. SEI formation, dissolution of Li y Mn2O4 particles) are modeled to account comprehensively for the behavior of a Li x C6–Li y Mn2O4 cell. The comparison between baseline and complex models is systematically used to analyze individual contributions and perform a deeper evaluation of the variables affecting the capacity fade with thermal inputs during typical cycle life tests. Some modifications in the original model are proposed to better describe the behavior of the cell and speed up the calculations.
