Ascend becomes first and only registrant of Trinohex® Ultra LIB electrolyte additive in China

HOUSTON,July 13,2022 -- Ascend Performance Materials' Trinohex® Ultra is now the first and only high-purity 1,3,6-hexanetricarbonitrile to be China REACH-registered,making the performance-boosting lithium-ion battery electrolyte additive available for use in the world's largest battery market.

Trinohex Ultra helps form a robust cathode-electrolyte interphase,making lithium-ion batteries safer,longer-lasting and perform better.

"China is at the forefront of lithium-ion battery production and we look forward to helping produce safer,longer-lasting and better-performing batteries," said Dave McNeece,sustainable specialties senior business manager at Ascend.

In third-party testing,Trinohex Ultra has demonstrated superior cathode protection across cathode and electrolyte chemistries. This protection has shown a 30% reduction in harmful gas generation and longer-lasting performance,especially in extreme conditions.

"Battery safety,performance,cost and material availability are the biggest obstacles to mass adoption of e-mobility and renewable energies," said Mr. McNeece. "Trinohex Ultra is a drop-in solution to these challenges and can be easily integrated into existing battery chemistries and manufacturing processes."

Trinohex Ultra is manufactured on world-scale assets and readily available globally.
