Title: Redox active colloidal particles for flow batteries

Abstract

The invention provides a redox flow battery comprising a microporous or nanoporous size-exclusion membrane, wherein one cell of the battery contains a redox-active colloidal particle dispersed in a non-aqueous solvent. The redox flow battery provides enhanced ionic conductivity across the electrolyte separator and reduced redox-active species crossover, thereby improving the performance and enabling widespread utilization of the battery. Redox active colloidal particles (RACs) were prepared, analyzed, and were found to be highly effective redox species for use in redox flow batteries.
