I do not know of any large format solid state batteries in production.  Not to say there aren't any.  This sounds new to me.  The question now is what battery company has been prototyping solid state batteries?  Probably more than one.  Anyway just looking for a prospective partner so I can get some of their stock before the price goes out of sight.
