Abstract

Procédé assisté par ordinateur de conception d’une électrode négative et dispositifs associés L’invention concerne un procédé de conception d’une électrode négative comportant : - au moins une optimisation d’une valeur d’au moins un paramètre parmi le jeu de paramètres relatifs à l’électrode négative à l’aide d’une technique d’optimisation, les autres paramètres présentant une évolution temporelle fixée, la technique d’optimisation comportant l’utilisation d’un modèle de vieillissement associant aux paramètres relatifs à l’élément électrochimique la performance électrique de l’élément électrochimique et la technique d’optimisation étant mise en œuvre sous la contrainte que l’élément électrochimique présente une valeur de performance électrique à respecter jusqu’à la fin d’un intervalle de temps d’utilisation, le jeu de paramètres optimisé étant l’ensemble des valeurs finales de chaque paramètre, la valeur finale étant soit la valeur initiale en l’absence d’application de l’optimisation audit paramètre soit la valeur optimisée.
