1-Butyl-1-methylpyrrolidinium bistriflimide is primarily used as an electrolyte additive in lithium-ion batteries to enhance thermal stability and ionic conductivity. It serves as a key component in supercapacitors due to its wide electrochemical window (>5V) and low viscosity. Researchers also employ it in electrodeposition processes and as a solvent for catalytic reactions. Its non-flammability makes it suitable for high-temperature applications where conventional solvents fail.
