Yes,  I saw that a few weeks ago.  I think it is safe to assume so.  Side reactions are due to moisture.  With a seperator that can take increased heat means thay can cure to a lower moisture level and get excellent cycle life as a result.  The side reactions are reduced and cell life increased.  With the current 44ah NMC cell Electrovaya has good energy density.  With a solid state cell they should be able to about double the energy density.
