| Zusammenfassung: | Redox flow batteries are an emerging technology for grid energy storage applications thanks to their promising properties, such as long cycle life and safety. Porous electrodes are a core component of flow batteries that facilitate the electron transfer between the liquid electrolyte and solid electrode by providing high specific surface areas. We are interested in macroscopic homogenized descriptions of the coupled processes of mass transport and heterogeneous reactions in porous electrodes, allowing for efficient simulations over macroscopic domains. The effective macroscopic properties, such as the dispersion tensor or the effective reaction rate depend on the pore-scale properties of the porous electrode, such as the morphology and surface properties of the electrode. Here we consider periodic porous media with simplified geometries. The electrolyte is modelled as a dilute, multicomponent mixture occupying the pore-space. We use the method of volume averaging for upscaling the pore-scale problem to obtain effective macroscopic descriptions and study their dependence on the pore-scale properties. In future work, we intend to consider more complex electrochemical interface descriptions based on the framework of non-equilibrium thermodynamics, which allow incorporating additional interface properties that could be provided by lower-scale descriptions, such as kinetic Monte Carlo simulations. |
