MODelling of Advanced LI Storage Systems

Project description

An advanced system to increase EV battery capacity

The EU battery sector faces significant challenges in a global, highly competitive environment. As the market of electric vehicles (EVs) and electronic instruments is growing, a new approach is needed that makes the development processes of next-generation battery systems cost-efficient. The EU-funded MODALIS2 project proposes an all-integrated development process that increases capacity and considerably reduces costs of EV battery cells. The goal of the project is to develop and validate modelling and simulation instruments for expediting the development of batteries with higher capacity and materials with improved performance. It aims to increase battery safety during transport and functioning, optimise cyclability and decrease production costs. The project will test and prepare the new cell generation with a high capacity of storage for mass production.

Objective

For a competitive EU battery sector, the development of next-generation battery systems needs cost-efficient processes. MODALIS² will make a significant contribution to a cost-down for EV battery cells through an all-integrated development process based on numerical tools relying on extensive measurement data and material characterization all the way down to micro-structures.

With the integrated modelling and simulation, MODALIS² will provide degrees of freedom for the cell and battery development processes that allows to address the following design challenges: i) faster development of batteries with higher energy density with new materials; ii) faster development of materials with higher optimized performances for higher-energy battery applications; iii) improved battery safety during transport and operation; iv) optimization of cyclability; v) lower development costs; and vi) better understanding of material interactions within the cell.

The main achievement of MODALIS² is to develop and validate modelling & simulation tools for Gen 3b cells by aiming for higher capacities for the positive & negative electrodes; and for Gen 4b cells by enabling the use of solid electrolytes for improved safety and to facilitate the use of Li-M for the negative electrode. These new technologies are submitted to new specific mechanisms and phenomena (mechanical stresses on negative electrodes, volumetric expansion, solid electrolytic conduction) that are not considered by current modelling and simulation tools.

MODALIS² will address the material characterization of next-generation (3b and 4b) Li-Ion cells in different physical domains, then expanding a carefully chosen set of models towards integrating new cell generations and implementing the models into a numerical simulations toolchain scalable to mass production. The modelling & simulation toolchain will allow faster time-to-market for next-gen cells.
