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
