LiFSI

LiFSI is a new type of electrolyte lithium salt suitable for the electrolyte of lithium batteries. It is environmentally friendly and has high safety performance. Compared with the most widely used lithium hexafluorophosphate (LiPF6), LiFSI has advantages in thermally stable (above 200℃) and conductive, and it also has advantages in industrial production conditions. It is currently the bestsubstitute for LiPF6 recognized at home and abroad, and has a good development prospect.
