Y134 is widely used as a high-performance additive in lithium-ion battery electrolytes. It enhances thermal stability and improves cycle life by forming a stable solid electrolyte interphase (SEI) layer on the anode surface. This results in reduced electrolyte decomposition and better performance at elevated temperatures. Y134 is particularly effective in batteries designed for electric vehicles and energy storage systems where safety and long-term reliability are critical. Its inclusion in electrolyte formulations helps suppress gas generation during charging, minimizing swelling in pouch cells. Additionally, Y134 contributes to improved low-temperature performance, making it suitable for use in a wide range of operating environments.
