| Use Pattern |
| Lithium Bis(fluorosulfonyl)imide (LiFSI, CAS 171611-11-3) is a widely used electrolyte additive in lithium-ion batteries due to its unique properties. LiFSI has high ionic conductivity and excellent solubility in a variety of organic solvents, contributing to improved overall electrolyte performance. It supports stable operation over a broad voltage range, which is particularly beneficial for high-energy-density batteries. |
