With the advent of electromobility, life cycle assessment studies need to keep up with growing number of cell formats and chemistries being adopted for various vehicle applications. This often hindered by lack of data. A model platform is presented, starting with a cell design computation model which is used for calculating the mass of cell components and other design parameters. It also includes a cell performance model, which will link to a battery pack and vehicle model, both used for estimate losses caused by the cell during vehicle operation. Furthermore, the platform comprises a model generating inventory data for life cycle assessment of lithium-ion battery cell production. Together, these parts feed information to life cycle assessment calculations covering both production and use of lithium-ion battery cells. The aim is to supporttechnology development and provide an understanding of how various design changes in cells link toenvironmental impacts. This conference paper explains model parts and provides exemplary results.
