Used in lithium-sulfur batteries as a liquid electrolyte formulation, consisting of 1.0M LiTFSI and 0.1M LiNO3 in a 1:1 volumetric mixture of DME and DOL solvents. It enables efficient lithium-ion conduction and supports the conversion reactions of lithium sulfide cathodes, contributing to high energy density and cycle life. This battery-grade electrolyte is designed for advanced rechargeable batteries in electric vehicles, portable electronics, and energy storage systems, offering good ionic conductivity while requiring careful handling due to the flammability of the organic solvents.
