Investigating the Redox Properties of a Bio-Inspired Vanadium-Based Non-Aqueous Flow Battery Electrolyte

摘要

Redox flow batteries (RFBs) have been identified as a promising large-scale energy storage technology to enable the transition toward a carbon-neutral electricity grid. Among various types of RFBs, non-aqueous redox flow batteries (NRFBs) have the potential to reach the energy density of lithium-ion batteries, while maintaining the advantages of flow systems, including decoupled power and energy rating and efficient long-duration storage. Despite the potential of this transformative technology, poor active material stability poses a fundamental obstacle to NRFB research progress. Furthermore, low active material concentrations negate high theoretical energy densities made possible by the wide electrochemical windows of non-aqueous electrolytes.
