Application Areas
1.Liquid Lithium-Ion Battery Electrolytes
2.Lithium Metal / Lithium-Sulfur / Lithium-Oxygen Batteries
The only compatible mainstream lithium salt for ether-based electrolyte systems. It effectively suppresses lithium dendrites, extends cycle life, and serves as a key raw material for high-end primary lithium metal batteries.
3.Solid-State / Gel Polymer Batteries
A standard raw material for PEO solid-state electrolytes and gel polymer electrolytes (GPEs). It enhances the ionic conductivity of solid-state membranes and is highly compatible with solid-state power batteries and micro-energy storage systems.
4.Ionic Liquids & Supercapacitors
Electrolytes for high-voltage electric double-layer capacitors (EDLCs) and hybrid supercapacitors. Features include a wide operating temperature range, long cycle life, and low self-discharge.
5.Perovskite Solar Cells (PSCs)
6.Fine Chemical Catalysis
Raw material for fluorine-containing Lewis acid catalysts, anion exchange reagents in organic synthesis, and antistatic materials.
