From the transcript.

"Our IP and patent position is increasing. Our next-generation battery development is being built upon some of our unique IP. We have an interesting technology development on a solid-state cell. A feasible solid-state battery is the Holy Grail in this energy transformation. Electrovaya, staff, we understand the complex chemistry that is needed for solid-state batteries and we are involved years ago on developing the world’s first commercial solid-state battery. For years Electrovaya’s technology was ahead of the market and now we are really gratified that the market has finally arrived and vindicated our years in creating this technology."

This make me think they have applied for a pattent on a new solid state cell and are waiting on the patent before making the announcement!  They seem to be waiting on something.....Anyway I think things will be better soooooon.
