The basis of these models consists of setting up a set of partial differential equations (PDEs) based on given physics laws, with the purpose of predicting the internal behavior of a cell under different conditions . A well posed and well-parametrized model can allow to study the evolution in time of these variables in a way that is not possible with our current in-operando experimental techniques applied to batteries . For example, some internal variables that are possible to track are; concentration of the alkali ion in the electrolyte and its metallic counterpart in the electrode. Additionally, the potential and current distributions in both the electrolyte and electrodes can also be traced.
