General description

Battery grade sodium bis(trifluoromethanesulfonyl)imide solution in ethylene carbonate, dimethylcarbonate, and ethylmethylcarbonate is a clear solution composed of a 1:1:1 volume ratio of three organic solvents - ethylene carbonate (EC), dimethyl carbonate (DMC), and ethyl methyl carbonate (EMC) - and 1.0 M concentration of sodium bis(trifluoromethanesulfonyl)imide (NaTFSI) as the electrolyte salt.

Application

The main application of 1.0 M NaTFSI in EC/DMC/EMC=1:1:1 (v/v/v), battery grade is as a electrolyte for sodium-ion batteries. We offer the superior electrolyte with controlled impurities, including water, acid, and trace metals content. Ethylene carbonate (EC) is known to form a stable, conductive solid electrolyte interphase (SEI) with many cathode and anode materials, including hard carbon and sodium metal oxides Ethyl methyl carbonate (EMC) and dimethyl carbonate (DMC) have lower viscosities and melting points than EC, and when mixed with EC result in an electrolyte with a good balance between desirable electrochemical properties, high dielectric constant, and low viscosity.
