The Breakthrough Electrolytes for Energy Storage (BEES) Energy Frontier Research Center (EFRC) has been established to develop an understanding of how the transport mechanism and electron transfer reactions occur in deep eutectic solvents (DES) and soft nanoparticle (SNP) systems, and how they can be controlled to advance electrochemical performance, from the atomistic level to the macroscopic level in a redox flow battery. Developing this fundamental know-how through synergizing experimental and theoretical investigations will enable design and synthesis of new electrolytes that will transform energy storage.
