Succinonitrile is widely used as an electrolyte additive in lithium-ion batteries due to its ability to enhance ionic conductivity and improve battery performance at low temperatures. It helps stabilize the electrolyte, reducing the risk of decomposition and extending the battery's lifespan. In addition, succinonitrile is employed in organic synthesis as a versatile intermediate for producing various chemicals, including pharmaceuticals and agrochemicals. Its high dielectric constant also makes it suitable for use in electrochemical applications and as a solvent in specialized reactions. Furthermore, it is explored in the development of solid-state electrolytes for advanced energy storage systems, offering potential for safer and more efficient batteries.
