GEN4 partial optimization In the news release it says « The final bar on the graph shows Novacium’s projection of potentially exceeding the 4,300 mAh mark with a blend of graphite and GEN4 partially optimized advanced silicon-based material. »
And at the end of the NR it links to NanoGraph NR in which it says « Our materials continue to exceed customer expectations, as we march towards our goal of a 4.3Ah 18650 cell, a project we have undertaken on behalf of the U.S. Department of Defense,” said Dr. Francis Wang, CEO of NanoGraf. “The 4.3Ah NanoGraf-branded cell will be the world’s most energy-dense 18650 cell and illustrates our commitment to meeting the energy and power demands of our customers. »
Obvioulsy the decision to do a partial optimization for GEN4 is not random. HPQ / Novacium are using as a waypoint, what others are using as a destination.
