Technology Marketing SummaryTypical electrolyte solvents for use in liquid or polymer electrolyte solutions include alkyl ethers and alkene carbonates. These solvents are used to dissolve electrolyte solutes and/or rubberizing polymer additives to form electrolyte solutions which may be used in electrochemical devices. However, these materials have significant disadvantages. Ethers are volatile and have low dielectric constants, while carbonates are unstable around alkali metals and have high melting points.DescriptionResearchers at Arizona State University have developed a new type of molecular solvent having an acidic boron atom as a key constituent. This solvent has such a wide electrochemical window and such powerful solvating properties that it is an excellent target solvent for alkali salts in rechargeable alkali metal anodes, high voltage cathodes, and voltaic cells. High-output electrochemical devices can be facilitated through use of this solvent.Applications and Industries•    Rechargeable Batteries
