There is as yet no software to help decision-makers decide on the impact of choosing a particular technology (in this case, a battery characterized by different metal assemblies). That's why a group from the University of Nancy, led by A.

It can associate a mass of raw materials with objectives set by users (the political decision-maker, a company, etc.) such as the proportion of electric vehicles or the targeted recycling rate. By using a multifactorial database on the chemical elements concerned, it will be possible to associate sustainability factors such as CO ₂ footprint, supply risk, proportion or reserve, production proportion, etc. Calculating...
