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. Particularly effective in high-voltage and high-temperature applications, helping maintain capacity retention over extended charge-discharge cycles. Also contributes to reduced gas generation during battery operation, improving overall cell reliability. Commonly used in high-performance batteries for electric vehicles and portable electronics.
