Application

Our 1.0 M NaTfO in diglyme, battery grade is an electrolyte designed for use in sodium-ion batteries (SIBs) and sodium superoxide (NaO2) batteries.[1,2] Studies have found that diglyme-based electrolytes can be used in sodium-ion batteries with graphite anode by overcoming the lack of suitable binary intercalation compounds in Na-C system.[3] Ether based electrolytes have the ability to trigger the highly reversible co-intercalation of sodium ions with an ether solvent into graphite, and form a stable solid electrolyte interphase (SEI).[4]

General description

Our battery grade sodium triflate solution in bis(2-methoxyethyl) ether (diglyme) is a clear solution containing 1.0 M sodium triflate dissolved in diglyme. To perform optimally in battery applications, we strictly minimize impurities including low moisture, low trace metals, low chloride, and low sulfate.
