Yes,  I have read an earlier article with the same information.  That brings up several questions in my mind.  Did Electrovaya share a few prototypes to Toyota and they have an agreed sale pending patent & UL certification?  Or did Toyota truely come up with this SS cell all on their own.  As for the production process.  That is a no brainer.  Toyota's wholey owned subsiderary is working with Electrovaya to finalise just such a process automation.  A process Electrovaya designed as they designed the cell so that it would be manufacturable.

So now we wait and see?!?
