Ascend Performance Materials and Samsung SDI have reached an agreement to end their ongoing global patent invalidation proceedings and enter into a patent license agreement regarding the sale and use of lithium-ion battery additives. Such additives include 1,3,6-hexanetricarbonitrile (HTCN), which is manufactured and sold by Ascend as Trinohex® Ultra.

As part of the agreement, Samsung SDI retains its U.S. patent no. 9,819,057, continues to hold patents in any remaining jurisdictions and grants Ascend a non-exclusive license under these patents. The specific terms and conditions of the agreement remain confidential.

A unique, non-hazardous nitrile, Trinohex Ultra is used to significantly improve battery life, safety and overall performance across cathode chemistries and voltages, even in extreme conditions.
