Nickel Tetra-(4-Sulfonatophenyl) Porphyrin/Ionic Liquid Supramolecular Assemblies for Applications in Symmetrical Aqueous Redox Flow Batteries.

ABSTRACT: Redox flow batteries (RFBs) are a promising technology as a grid-level energy storage system and have attracted a growing amount of attention. In these devices, electrochemical storage is carried out through the reduction and oxidation of chemical species. The peculiarity of RFBs is that active species are in solutions, with the reaction occurring at the solid-liquid interface. In the present work, we propose the use of nickel tetra-(4-sulfonatophenyl)-porphyrin (NiTPPS) as an innovative bipolar redox-active molecule (BRM) for aqueous organic redox flow batteries (AORFBs). Thanks to its distinctive redox properties, this single yet complex molecule serves as both an anolyte and a catholyte. This symmetry allows RFBs to use identical components, offering simplified storage and reduced cross
