Used as electrolyte additive in lithium batteries

Stanyl® SN-PURE is high-purity Succinonitrile, an electrolyte additive in lithium-ion batteries that improves overall battery safety and extends service life via the reduction of harmful gas generation. Battery life performance is extended because Stanyl® SN-PURE increases the lifetime of Nickel (Ni), Manganese (Mn) and Cobalt (Co) cathode chemistries.Envalior is the largest producer of Succinonitrile, and Stanyl® SN-PURE compound forms a protective layer at the cathode to suppress electrolyte decomposition, protect against oxidation and prevent dendrite formation.The compound offers:- High purity of 99.95% and low ion concentration to optimize battery performance- Superior thermal stability over long operation times- <2000 parts per million (ppm) water content to lower the risk of oxidization- Freezing point of 57.2°C and high boiling point of 266°C to withstand extreme temperatures- In the battery application it acts as non-hazardous chemistry to prevent harmful gases from forming- Compliance with key regulations for battery system manufacturing- Global availability at mass scale to mitigate any supply chain risks
