dc.description.abstractRedox flow batteries are an emerging technology for large-scale grid energy storage of intermittent renewable energy sources, such as photovoltaics and wind farms, thanks to their beneficial properties, such safety and long cycle life. Specifically, organic redox flow battery (ORFB) systems are a promising approach for electrical energy storage. This is due to the vast chemical space available for electro-active redox couples and the prospect for greater sustainability. To describe and simulate the main processes within a flow battery cell we developed the spatially reduced physics-based 0D-U-I-SoC cell model. To extend the predictive capabilities of the reduced cell model we develop a transient, non-isothermal cell performance model that captures spatial inhomogeneities of the field variables, such as the species concentrations in the porous electrodes. The physics-based macrohomogeneous cell model solves the balance laws for mass, momentum, and energy transport in the current collectors, the porous electrodes, and the ion-exchange membrane. To account for the effective macroscopic transport properties in the porous electrodes, such as effective diffusion coefficient, we integrate a porous electrode model based on the volume averaging method. Additionally, we develop an effective membrane model that accounts for all important modes of transport including osmosis and the electro-osmotic drag. The model is parameterized and validated with experimental data of laboratory test cells for promising organic molecules and subsequently used to study and optimize the energy efficiency with respect to the cell geometry and operating condition, such as flow rate and ambient temperature. Furthermore, the model is used to predict time-dependent phenomena, such as EIS measurements and voltammetry experiments.de_CH
