Aqueous interphase formed by CO2 brings electrolytes back to salt-in-water regime

by Jinming Yue

Nature Chemistry, Published online: 11 October 2021; doi:10.1038/s41557-021-00787-y

Super-concentrated water-in-salt electrolytes enable high-voltage aqueous batteries, but have considerable drawbacks such as high viscosity, low conductivity and slow kinetics. Now a concentration-dependent association between CO2 and TFSI– has been discovered and leveraged to decouple the interphasial responsibility of an aqueous electrolyte from its bulk properties, making high-voltage aqueous Li-ion batteries practical in dilute salt-in-water electrolytes.
