Used as a high-polarity solvent in lithium-ion battery electrolytes due to its excellent solvating ability for lithium salts and good ionic conductivity. It helps form a stable solid electrolyte interphase (SEI) on the anode, improving battery cycle life and safety. Also serves as an intermediate in the production of ethylene glycol and other carbonate esters. Employed in gas treating processes to remove acidic gases like carbon dioxide and hydrogen sulfide from natural gas and industrial streams. Its biodegradability and low toxicity make it suitable for use in environmentally friendly formulations.
