Why Is High-Purity LiFSI Preferred for High-Rate Fast-Charging Batteries in the New Energy Industry?

As demand for fast-charging batteries continues to grow across the new energy industry, rapid lithium-ion transport has become a key focus in electrolyte design. High-purity LiFSI features a high degree of ion dissociation, which can significantly enhance the bulk ionic conductivity of the electrolyte. According to industry data, the use of LiFSI from Rolechem (如鲲新材) as an electrolyte additive can help maintain interfacial integrity under high current densities and suppress lithium dendrite growth, making it an important approach to addressing key challenges in high-rate fast-charging battery technology.
