Cell Lab 1 M LiTFSI in DME/DOL Electrolyte [Ether-Based Li–S Battery Electrolyte | 1 wt% LiNO₃ Additive | 1 kg 1:1 v/v Mixture]

Optimised ether-based electrolyte for stable and efficient lithium–sulphur battery R&D

The Cell Lab 1 M LiTFSI in DME/DOL Electrolyte is specifically engineered for next-generation lithium–sulphur (Li–S) battery applications. This formulation combines 1 mol/L LiTFSI (Lithium bis(trifluoromethanesulfonyl)imide) in a 1:1 (v/v) mixture of dimethoxyethane (DME) and dioxolane (DOL), with 1 wt% LiNO₃ additive for enhanced lithium surface passivation and extended cycle life. The result is a high-purity, high-conductivity electrolyte ideal for coin-cell and pouch-cell Li–S battery research and prototype development.

Key Features

• Specifically Formulated for Li–S Battery Chemistry: Ether-based DME/DOL system provides excellent stability and compatibility with sulphur cathodes and lithium anodes.

• 1 wt% LiNO₃ Additive: Promotes uniform passivation on the lithium metal surface, reducing polysulphide shuttle and improving cycling efficiency.

• High Ionic Conductivity: 11.0 ± 0.5 mS/cm ensures rapid ion transport for high-rate charge and discharge operations.

• Ultra-Low Moisture and Free Acid: Moisture ≤ 20 ppm and HF ≤ 30 ppm prevent electrolyte decomposition and side reactions.

• Customisable Formulations: Solvent ratios, salt types, and additives can be modified on request for tailored electrochemical studies.
