Used as an electrolyte additive in lithium-ion batteries to improve cycle life and thermal stability. Enhances the formation of a stable solid electrolyte interphase (SEI) layer on the anode, which reduces electrolyte decomposition and increases battery safety. Also helps in lowering internal resistance and improving charge-discharge efficiency, especially at high voltages and elevated temperatures. Applied in advanced battery systems for electric vehicles and portable electronics where long-term performance and reliability are critical.
