Product Overview
This high-purity lithium hexafluorophosphate solution serves as an essential, high-performance electrolyte for next-generation lithium-ion battery research, cell fabrication, and electrochemical testing. Formulated with a precise 1.0 mol/L salt concentration dissolved in balanced organic carbonate solvent matrices, this specialized chemical solution delivers superior ionic conductivity, robust electrochemical stability, and optimal lithium-ion transference numbers required for cutting-edge energy storage development.
Engineered specifically for laboratory-scale prototyping, academic materials research, and industrial pouch or coin cell assembly, the liquid electrolyte supports seamless solid electrolyte interphase formation across both graphite and advanced silicon-composite anodes. By providing reliable passivation on positive aluminum current collectors across standard operating voltages, this solution empowers researchers to evaluate electrode formulations, separator coatings, and cathode active materials with utmost analytical consistency.
Due to the intrinsic chemical sensitivity of hexafluorophosphate salts toward ambient moisture and hydrolytic decomposition, this chemical product is strictly packaged in hermetically sealed stainless steel vessels. This ensures moisture-free integrity from shipping to laboratory dispensing, guaranteeing reproducible cycling life, minimized internal resistance growth, and exceptional data fidelity across demanding electrochemical protocols.
Key Features
- Precise 1.0 M Salt Concentration: Standardized 1 mol/L lithium hexafluorophosphate concentration ensures consistent ionic mobility and optimal ion pairing dynamics, providing reproducible baseline data for comparative electrochemical studies.
- Multiple Optimized Carbonate Formulations: Available in binary and ternary organic carbonate mixtures—including EC/DEC, EC/DMC, EC/DMC/DEC, and EC/DMC/EMC—to accommodate tailored viscosity requirements, dielectric constants, and operating temperature profiles.
- Superior Aluminum Passivation: Forms a stable, highly protective passivation layer on positive aluminum current collectors, preventing anodic corrosion at high operational potentials above 3.8 V during sustained cycling.
- Optimized SEI Film Formation: Carefully balanced ethylene carbonate (EC) solvent ratios facilitate the formation of a dense, low-impedance solid electrolyte interphase on negative electrode surfaces, effectively preventing continuous solvent co-intercalation.
- Hermetic Stainless Steel Packaging: Sealed in robust, air-tight stainless steel containers to completely isolate the moisture-sensitive electrolyte from ambient humidity, preventing premature degradation and hazardous hydrofluoric acid formation during storage and transit.
- High Electrochemical Window Stability: Delivers dependable oxidation resistance and broad electrochemical stability across the standard operational potential range of commercial and experimental cathode chemistries.
- Strict Quality Control Standards: Prepared under ultra-low moisture and oxygen environments to minimize trace water content, directly suppressing hydrolytic reactions and ensuring low parasitic side reactions in assembled test cells.
