Description
Lithium-Sulfur Battery Electrolyte (1M LiTFSI in DME:DOL 1:1 + 1% LiNO₃)
The Lithium-Sulfur Battery Electrolyte is a high-purity liquid electrolyte specifically engineered for advanced Li-S battery systems. It features a balanced solvent system of DME (Dimethoxyethane) and DOL (1,3-Dioxolane) in a 1:1 volume ratio, combined with 1M LiTFSI (Lithium bis(trifluoromethanesulfonyl)imide) salt and 1% LiNO₃ additive.
This formulation effectively addresses key challenges in lithium-sulfur batteries, including the polysulfide shuttle effect, electrolyte stability, and lithium anode protection, making it an essential material for both battery R&D laboratories and pilot-scale production lines.
