Fundamental Understanding and Engineering of the Highly Concentrated Aqueous Electrolyte
Deep decarbonization of the US electric grid will require a TWh-scale of low-cost electrochemical energy storage to accommodate the intermittencies from massive renewable energies. The electrolyte is one of the most critical components in an energy storage system. This presentation describes the development of highly concentrated aqueous electrolytes with their applications in redox flow batteries as the only battery architecture able to decouple power from energy for long-duration energy storage. Fundamental topics of the aqueous electrolyte, such as solvation chemistry, proton regulation, and molecular engineering of the active species, will be discussed. Such understanding is pivotal in developing advanced electrolytes for next-generation energy storage.
