Used as a lithium salt in electrolytes for lithium-ion batteries, enhancing thermal stability and electrochemical performance. Its fluorinated imidazole structure improves conductivity and supports stable solid-electrolyte interphase (SEI) formation on electrode surfaces. Commonly applied in high-voltage and high-temperature battery systems where safety and cycle life are critical. Also explored in lithium-metal and solid-state batteries for its ability to suppress dendrite growth and reduce side reactions.
