1.0M LiTFSI in DOL/DME=1:1 (v/v) with 1% LiNO3 Lithium-Sulfur Battery Electrolyte (KLD-S02)

This electrolyte formulation, designed for lithium-sulfur battery research, consists of 1.0 M lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) dissolved in a 1:1 volumetric mixture of 1,3-dioxolane (DOL) and dimethoxyethane (DME), with 1.0% lithium nitrate (LiNO₃) as an additive. The LiNO₃ additive plays a critical role in suppressing polysulfide shuttling and stabilizing the lithium metal anode, a key challenge in lithium‑sulfur systems. With a moderate molar concentration and optimized solvent ratio, this electrolyte balances ionic conductivity and electrochemical stability. It is commonly employed in laboratory‑scale coin cells and pouch cells for evaluating sulfur‑carbon composite cathodes, lithium‑metal anodes, and advanced separator materials. The product is available in multiple mass options—50 g to 1000 g—accommodating both initial screening and extended cycle‑life testing in academic and industrial R&D settings.
