Redox Flow Batteries: MetILs³: A Strategy for High Density Energy Storage Using Redox‐Active Ionic Liquids (Adv. Sustainable Syst. 9/2017)

Nonaqueous redox flow batteries (RFBs) hold the potential for high energy density grid scale storage, though are often limited by the solubility of the redox-active species in their electrolytes. In article number 1700066, a systematic approach for increasing the concentration of redox-active species in electrolytes for nonaqueous RFB, starting from a metal coordination cation-based ionic liquid is presented, by Leo J. Small and co-workers. Cover graphics prepared by Vicente Garcia.
