Fluorinated Carbonates

Halocarbon can provide you with unique symmetrical and unsymmetrical fluorinated carbonates that provide the following benefits in high voltage applications:
• improved SEI layer formation
• improved capacity retention
• enhanced oxidative stability, allowing use at high voltage ranges (4.2V-5.0V)
• flammability suppression
