Titre :Designing High-Performance Redox Flow Batteries for Long-Duration Energy Storage

Résumé: Redox flow batteries (RFBs) are an emerging energy storage technology that offers unique advantages for long-duration, grid-scale energy storage due to their ability to decouple energy and power ratings and the associated unprecedented scalability. Despite their promise, the relatively higher capital cost of RFBs limits their commercial viability and widespread adoption. One possible approach to reduce the capital cost is to improve the performance (i.e., increased energy and/or power density) of state-of-the-art systems for less material use, which consequently reduces cell costs. In this talk, an overview of the presenter’s most recent research toward high-performance RFBs will be given. In particular, the following three research projects will be summarized:

    1. Natural selection as a toolkit to overcome practical limitations in non-aqueous redox flow batteries (NRFB) – The performance characteristics of the mushroom inspired NRFB electrolyte using a suite of electrochemical and operando spectro- lectrochemical data will be reported.
    1. Overcoming the active material solubility limitation in RFBs via redox-targeting reactions – Recent efforts to reveal the fundamental principles of indirect redox-targeting reactions necessary to enable the rational design of high-energy density RFBs will be presented.
    1. Manufacturing of fabric-electrodes using machine learning based screening platforms – Critical factors underpinning electrode performance are elucidated. The key physico-chemical properties of various types of electrodes and their evolution during cycling will be discussed.
