Extension of Open EM Modeling Platform Towards Electrochemistry and Energy Materials

The paper reports recent developments of Open Innovation Environments in a focus of the European Union research projects. It presents a new extension of the open access computational electromagnetics platform to the modeling of coupled electrochemical phenomena occurring at electrolyte/electrode interfaces. The problems are solved using coupled Laplace / Poisson and drift-diffusion equations, which create a basic model of ion transport process in the electrolyte, as in e.g. in popular Li-ion batteries. The developed coupled FDTD solver is validated against analytical solutions for the electrostatics and independent FEM solutions for the electrochemistry. It is prepared to be openly used for the modeling of industrially representative test-fixtures for battery materials, such as those defined in the H2020 NanoBat project.
