The greenSPEED projects ambition is to create a safe, long-lived, high-capacity battery cell, while reducing the carbon footprint and environmental impact during its production. This will open the opportunity for cheaper and “greener” mobile electric applications.
Focusing on the development of a new generation of lithium (Li) ion battery cells, containing specially treated copper and aluminium foils as current collectors and promising silicon-based anode material. Tests are carried out on pouch cells and cylindrical cells (21700) and are supported by finite element model (FEM) simulations
Tensile tests are done for the different cell components to obtain material parameters for FEM simulations. The specific material models will be used to assemble a cell model to propose improvements for cell design and the overall mechanical properties of the cell.
The newly developed battery cells will additionally be tested for their expansion behaviour under varying conditions and the data will be used to parameterise an expansion model which will be used for the cell simulations. The combination of material specific models and expansion model will lead to simulations which give insight in the mechanical behaviour of the battery cell and stress distribution during charge and discharge. This toolchain will increase the development speed and provides a modular framework for further investigations.
