Overview
LiDFOB forms stable SEI/CEI films on both anode and cathode, improving high-temperature storage, high-voltage and cycling performance. It is commonly used in high-voltage NCM, silicon-based anode and LTO systems, typically at 0.5%–3%.
- High film-forming efficiency
- Improves high temperature and high voltage
- H₂O ≤ 50 ppm
