Ex-situ and In-situ EPR and NMR studies of energy materials
EMSL Project ID
61044
Abstract
Redox flow batteries have a unique architecture that enables long-duration energy storage, which is a potential solution that addresses the intermittency introduced by increased renewable energy integration into the electricity grid to achieve decarbonization of the electric power sector. We have successfully demonstrated that fluorenone-based flow batteries with the organic additive, β-cyclodextrin, exhibit enhanced rate capability, high capacity, and long cycling. However, in order to in-situ monitoring the oxidation status and speciation change of the fluorenone molecules and radicals as well as the interactions between the additvities and fluorenones during the battery discharge and charge processes, we will need EPR and NMR at EMSL, especially in-situ EPR and flow NMR. Furthermore, when polymers are introduced into the flow batteries, high-field solid-state NMR will provide valuable structure and dynamic information on these battery materials.
