NOVEL ORGANIC MATERIALS FOR NON-AQUEOUS REDOX FLOW BATTERIES: IMPLEMENTATION OF TRIARYLAMINE AND PHENAZINE CORE STRUCTURES

Abstract

The rapid growth of the role of renewable energy sources dictates new requirements for the electrochemical energy storage devices. Among them, redox flow batteries (RFBs) are regarded as a promising technology, since their advantages of excellent scalability, low cost, easy fabrication and operation, long lifetime, and safety. Today inorganic RFBs are penetrating the market, however, low specific capacity in conjunction with with low electrochemical stability window of aqueous electrolytes (≈1.5 V) and safety issues, hinders their wide-scale commercialization.
