I guess I would have just assumed that because batteries are chemistry the size scales relatively easily.

Anyways- isn't a normal cell in an EV battery is like a AA size? Is this still true for solid state?



> isn't a normal cell in an EV battery is like a AA size?

No. Some companies use tons of cylindrical cells that are larger AAs (like 18mmx65mm, 21mmx80mm, or 46mmx80mm). But even then at 46mm in diameter it's a good bit bigger than a AA.

But lots of manufacturers use prismatic or pouch like batteries. They're large and rectangular. Like these batteries on this BYD, they're called "blades". Most other major manufacturers use prismatic cells.
