ELECTROCHEMICALLY-MEDIATED LI~+ CHELATION BY 1,2,3,4-TETRAHYDRO-6,7- DIMETHOXY-1,1,4,4- TETRAMETHYLNAPHTHALENE: IN SITU STRUCTURAL CHARACTERIZATION AND ENERGY STORAGE APPLICATIONS

摘要

Long-term stability of newly developed yet relatively unproven materials for charge storage in organic redox flow batteries (RFBs) is a concern of paramount importance because the expected device lifetime of RFBs exceeds 10 years. Interactions between organic moities and electrolyte components can influence electrochemical properties and are thus important considerations in establishing design rules for new charge storage materials. Accordingly, the demonstration of scientific approaches capable of elucidating dynamic structural changes in complex chemical matrixes is of broad interest to the energy storage community. We examined the structural changes accompanying the electrochemical oxidation of 1,2,3,4-tetrahydro-6,7-dimethoxy-1,1,4,4-tetramethylnaphthalene (TDT), a promising organic positive electrode material for non-aqueous RFBs using a combined experimental and theoretical approach.
