Primarily utilized in the formulation of electrolytes for lithium-ion batteries, FIMC serves as both a solvent and additive, enhancing electrochemical performance. It helps deliver high ionic conductivity and promotes the formation of a stable cathode electrolyte interphase (CEI) on high-voltage cathode materials. In tests, cells containing 25% FIMC demonstrated reduced polarization, lower impedance, and increased discharge capacities than cells without FIMC, particularly at lower temperatures.
