lithium-ion battery additives. Such additives include

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.
