Used primarily as an ionic liquid in electrochemical applications due to its high ionic conductivity and thermal stability. Commonly employed as an electrolyte component in lithium-ion and sodium-ion batteries, where it enhances electrode performance and cycle life. Its wide electrochemical window allows operation at high voltages without decomposition. Also utilized in dye-sensitized solar cells and supercapacitors for improved charge storage and efficiency. Serves as a green solvent in organic synthesis, facilitating reactions under mild conditions with easy product separation. Shows promise in carbon dioxide capture and gas separation technologies owing to tunable polarity and low volatility.
