- 요약This thesis investigates the performance and scalability of microtubular vanadium redox flow batteries (VRFBs), addressing key factors such as ohmic resistance, electrode configuration, and material selection. A systematic approach combining experimental studies, analytical modeling, and numerical simulations provides critical insights into the challenges and opportunities for advancing microtubular reactors. Chapter 2 explores the effect of electrode porosity and configuration on ohmic losses. Experimental work demonstrates that the conductivity of the electrode and the uniformity of the current distribution are crucial for minimizing area-specific resistance (ASR). Although coaxial configurations reduce areal resistance, they may lead to higher volumetric resistance (VSR), suggesting that a quasi-coaxial configuration may be better suited for multitubular flow batteries. Chapter 3 presents the development of an analytical model for tubular reactors, which highlights the impact of electrode geometry and material properties on current distribution, electrode utilization, and ASR scaling. The model identifies key dimensionless parameters that govern current distribution and provides a foundation for optimizing reactor design before more complex computational methods are employed. Chapter 4 focuses on enhancing the scalability of microtubular VRFBs through material selection, specifically introducing bare copper as a promising anode material. Copper's high conductivity, stability in vanadium electrolytes, and low cost make it a strong alternative to graphite, especially for larger-scale applications. Copper demonstrates superior performance and scalability compared to graphite-based anodes. In conclusion, this thesis advances the field of electrochemical reactor design by optimizing electrode configurations, developing analytical tools, and selecting suitable materials for scalable microtubular VRFBs. The insights gained from this work contribute to the development of next-generation energy storage solutions, which are critical for the integration of renewable energy into power grids.
