Abstract
The main objective of this thesis is to optimise the fabrication process of a pouch cell based on physico-chemical modelling and characterisation. To achieve this objective, a characterisation procedure based on physico-chemical measurements was developed. Then, the cross-linked influences of the battery fabrication process parameters and final cell performance were evaluated based on the previously developed procedure. Finally, a model-based optimisation methodology for inverse cell design was proposed and validated. Among the contributions of this thesis, two points can be highlighted. On the one hand, a new characterisation protocol for a pseudo-two-dimensional model of commercial and prototyping pouch cells was validated. On the other hand, an inverse cell design methodology was proposed based on design of experiments and electrochemical modelling.
