Lithium-ion battery additive Trinohex® Ultra earns REACH approval in Korea
Ascend Performance Materials’ electrolyte additive for lithium-ion batteries has earned REACH approval in Korea, further expanding the availability of this unique material. Trinohex超, manufactured in the United States by Ascend, is now approved for import into Korea in quantities up to 1,000 metric tons annually per REACH, the regulation for registration, 评价, and authorization of chemicals in the region.
Covered by an extensive patent portfolio, Trinohex超 is a high-purity 1,3,6-hexanetricarbonitrile designed to increase the life cycle and improve the safety of high-voltage lithium-ion batteries, such as those used in electric vehicles. It works by forming a protective film around the cathode, which prevents metal ion dissolution and decomposition of the electrolyte, 从而更安全, longer-lasting batteries.
Higher voltages enable faster charging and longer range in electric vehicles. But that increased voltage also increases the rate of decomposition and degradation which leads to an increase in transition metals and eventually anode poisoning, 戴夫·麦克尼斯说, the business director for Ascend’s sustainable specialties division.
“For battery producers, achieving reliable performance at high voltage has been challenging,麦克尼斯说. “Trinohex超 helps slow down the negative effects of transition metal ions with a higher overall voltage stability, allowing cell manufacturers to reach their voltage goals, improve the overall performance of their cells and increase cycle life.”
Trinohex超 has demonstrated superior cathode protection across cathode and electrolyte chemistries in third-party testing. This protection has shown a 30% reduction in harmful gas generation and longer-lasting performance, especially in extreme conditions.
“Korea produces more than one-fifth of the world’s EV battery capacity,麦克尼斯说. “The expanded import volumes will allow us to support those manufacturers better as they create innovative batteries that work without performance dips associated with the next generation of battery technologies.”
Trinohex超 is manufactured on world-scale assets and is readily available globally. Ascend previously announced expanded REACH registration in 欧洲 and China, and the company continues to pursue new and expanded chemical inventory registrations throughout the world.
