Product Overview
This high-purity battery electrolyte is specifically formulated for lithium-sulfur (Li-S) and next-generation lithium metal battery research. Composed of lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) dissolved in a precision-blended binary ether solvent mixture of 1,2-dimethoxyethane (DME) and 1,3-dioxolane (DOL), this chemical solution provides the ideal solvating environment for complex sulfur cathode electrochemistry. The specialized formulation promotes high lithium-ion mobility and suppresses excessive concentration polarization during charge-discharge cycling.
Engineered to address the fundamental challenges of sulfur utilization and polysulfide intermediate dynamics, this electrolyte system is essential for electrochemical laboratories, academic research centers, and energy storage pilot lines. The baseline ether solvent composition provides the required dielectric constant and low viscosity to facilitate rapid ion transport across porous sulfur-carbon composite electrodes and separators.
Manufactured under stringent moisture-controlled protocols, this liquid electrolyte guarantees exceptional reproducibility across coin cells, split test cells, and multi-layer pouch cells. To maintain optimal electrochemical properties and prevent ambient moisture contamination, all handling and cell fabrication operations must be conducted strictly within vacuum, dry room, or inert-gas glovebox environments.
Key Features
- Superior Anion Delocalization and Ion Dissociation: The large, flexible bistriflimide anion [N(SO2CF3)2]− features extensive negative charge delocalization across its sulfonyl groups, effectively reducing ion-pairing tendencies and delivering remarkably high lithium cation transference numbers compared to conventional inorganic lithium salts.
- Optimized Binary Ether Solvent Matrix: The 1:1 volumetric blend of 1,2-dimethoxyethane (DME) and 1,3-dioxolane (DOL) combines high polysulfide solubility with low bulk viscosity, facilitating rapid wetting of thick cathode structures and lowering interfacial charge-transfer resistance.
- Effective Lithium Anode Passivation: Available with standard 1 wt% lithium nitrate (LiNO3) additive, this formulation promotes the formation of a robust, protective solid electrolyte interphase (SEI) on metallic lithium anodes, effectively suppressing the parasitic polysulfide shuttle effect and extending cell cycle life.
- Enhanced Thermal and Electrochemical Stability: Unlike legacy salts such as LiClO4 or LiAsF6, this imide salt structure exhibits exceptional resistance to thermal degradation and oxidative decomposition, ensuring stable operation across standard Li-S operating voltage windows.
- Reduced High-Rate Polarization: The combination of elevated ionic conductivity and low ionic association minimizes concentration gradients across the inter-electrode gap, allowing high-rate cycling without premature voltage cutoff in demanding test protocols.
- Ultra-Low Trace Moisture Content: Prepared under strictly controlled dry conditions, the solution maintains trace water and impurity levels below critical detection thresholds to prevent premature lithium foil corrosion and active material degradation.
- Flexible Tailored Formulations: Available in standard optimized concentrations or fully customizable ratios, allowing battery researchers to adjust salt molarity, ether proportions, and additive chemistries to target specific electro-catalytic, low-temperature, or high-areal-capacity benchmarks.
