Abstract
In this work an electrochemical model combined with an aging model based on SEI formation is developed. Galvanostatic cycling and impedance tests are performed to optimize the cell model by determining parameters for which there is no consensus in literature. The electrochemical model is a P2D model while the aging model is a 0D model. Besides being the first work concerning modeling of LMNO-Graphite cells, relevant aspects of this approach are related to experimental estimation of most parameters involved; a two-steps validation that allows to obtain more significant values of non-experimental parameters (with high accuracy of results); the ability to simulate precisely the spectrum phenomena occurring within the cell and the possibility to consider the Coulombic efficiency of the system.
