Solid-state

No car in this database uses solid-state cells, because none is on sale to the public anywhere. The chemistry is documented here anyway, because it is the most frequently promised improvement in electric cars and the promise is reported as though it were a product. What is actually demonstrated, what is in pilot production and what is still a press release are three different things, and the solid-state reference separates them with dates. This archive will fill itself the moment a car in the database ships with these cells; until then an empty list is the correct answer and no estimate stands in for it.
