The main achievement and contribution of MODALIS² is to develop and validate modelling and simulation tools for the following next generation batteries:
- Gen 3b: aiming for higher capacities for the positive and negative electrodes. The new materials used in this technology are challenging in terms of modelling due to their high volumetric expansion which will require specific new development in order to account for this phenomenon at material and cell level. Specific care will be taken to model the interfaces and their behaviour during volumetric expansion.
- Gen 4b: enabling the use of solid electrolytes for improved safety and to facilitate the use of Li-M for the negative electrode. These solid electrolytes will require new developments in order to account for the specific mechanisms responsible of solid state ionic conductivity as well as the interfacial phenomena occurring in hybrid solid electrolytes and at the interface between active material and electrolyte.
MODALIS² will add relevant effects for next Gen Lithium Ion batteries to state-of-the-art simulation tools. This will enable industry to incorporate new and innovative materials within their next generation Lithium Ion battery cells.
MODALIS² will provide degrees of freedom for the cell and battery development processes that will then allow to address the following design challenges:
- The need for faster development of batteries with higher energy density with new materials
- The need for faster development of materials with higher optimized performances for higher-energy battery applications
- Improved battery safety, both during transport and operation
- Optimization of cyclability by using MODALIS² tools
- Lower development costs
- Better understanding of material interactions within the cell
