UW-Madison Department of Materials Science and Engineering welcomes this week’s seminar speaker, Assistant Professor Dawei Feng. The seminar on “Experimental Data-Driven and Thermodynamics-Informed Approaches for Redox Flow Batteries in Grid Energy Storage with Boosted Performances” will be on Thursday, Sept. 12 in MS&E 265 from 1 p.m. to 2 p.m.
Abstract
With the growing integration of renewable energy sources, the need for efficient, large-scale energy storage solutions becomes increasingly vital for grid stability. Redox flow batteries (RFBs) are a leading candidate for this role, offering scalability and flexibility. This talk presents two innovative approaches to advancing RFB technology for grid energy storage.
In the first approach, we perform extensive manual data collection through high-throughput synthesis and testing of aqueous organic redox flow batteries. This method enables the rapid identification and optimization of redox-active molecules that exhibit improved energy density and enhanced cycling stability, addressing the key challenges of large-scale energy storage.
In the second approach, we employ thermodynamic analysis to guide the development of halide-based flow batteries with exceptional stability and energy density. By introducing organic molecular additives, such as ZIT (Zwitterionic Trapper), we significantly enhance the cycling stability and energy performance of these systems.
Through the combination of data-driven experimentation and physics-informed predictive models, these strategies provide new insights and practical pathways for designing efficient and long-lasting redox flow batteries, paving the way for their role in sustainable grid energy storage.
