Trinohex Ultra

Trinohex® Ultra is high-purity 1,3,6-hexanetricarbonitrile, an electrolyte additive proven to improve the performance and extend the life of high-voltage lithium ion batteries. Trinohex Ultra works by forming a protective film around the cathode, which prevents metal ion dissolution, decomposition of the electrolyte and hydrogen fluoride attack on the cathode.
