Ascend Performance Materials, a US-based materials manufacturer, has received approval of a new electrolyte additive for lithium-ion batteries to increase its imports into the EU.

Trinohex Ultra is approved for import into the EU in quantities up to 100 metric tons annually under REACH, the regulation for registration, evaluation and authorization of chemicals in the region. Trinohex Ultra is a high-purity 1,3,6-hexanetricarbonitrile designed to increase the cycle life and improve the safety of high-voltage lithium-ion EV batteries, said the company. It forms a protective film around the cathode, which prevents metal ion dissolution and decomposition of the electrolyte. In third-party testing, Trinohex Ultra has demonstrated cathode protection across cathode and electrolyte chemistries.

“The expanded import volumes will allow us to support the production of more than 200,000 new EVs each year,” said Dave McNeece, Business Director at Ascend.
