Lithium ion battery solutions
Lithium-ion batteries are the core energy source for EVs, ESS and mobile devices, and as energy density rises the challenges of electrolyte stability and safety intensify. Halocarbon's fluorinated electrolyte additives and co-solvents are designed to protect the electrolyte under high-voltage, high-temperature conditions and to lift cell life and safety together.
How fluorinated additives change cell behavior
- Improved electrolyte stability · reduced high-voltage (>4.3V) decomposition
- Cell-component compatibility · improved charge transport
- Optimized SEI layer formation · reduced initial-cycle loss
- Reduced gas generation · suppressed cell swelling
