OPTIMIZING POROUS ELECTRODE ARCHITECTURE: LEVERAGING PORE NETWORK MODELING TO ENHANCE FLOW BATTERY PERFORMANCE

Enhancing the performance of electrochemical cells, such as flow batteries, necessitates the design of optimized electrode structures that effectively balance various interacting physical phenomena. This study presents an integrated approach that combines mathematical optimization with pore-scale modeling to tailor electrode architectures. By employing a pore network model in conjunction with a metaheuristic algorithm, the study seeks to maximize the overall reaction rate by systematically altering the pore network morphology. A proof-of-concept investigation, conducted within a design domain characterized by millimeter-scale dimensions and micron-scale pore resolution, illustrates the effectiveness of the proposed framework in generating optimized porous reactors. These optimized reactors demonstrate enhanced conversion rates and reduced pumping costs, attributable to superior pore network configurations, thereby contributing to the development of high-performance porous electrodes.
