In order to be able to rapidly and efficiently improve modern electrode materials in terms of performance and energy efficiency, the use of the new multi-scale modeling method at a microporous level in the SimPore project is tested together with the project partner VIRTUAL VEHICLE Research Center. For this purpose, "double porosity" models – known from geology for, among other things, the calculation of contamination in groundwater – are applied to electrochemical energy storage. For the purpose of parameterisation and validation, a known cathode material for Li-ion cells with different micropore and macropore ratios is produced and characterised at the AIT. Finally, simulations verify the meaningfulness of this modeling approach as an optimisation tool for microporous battery materials.
