    Problems include the extreme sensitivity of the batteries to moisture and oxygen, as well as the mechanical pressure needed to hold them together

    Not quite the ideal thing to have in a real world car. For example, what happens after a little accident leaves an opening in the hull of such a battery? Or creates some more pressure than needed here and there?

              No, but it’s the difference between solid state and lithium cells. There’s still a fire risk with solid state, but then there’s a fire risk with ICE. It just needs better engineering like they’ve done with current ev batteries

                That isn’t what’s being discussed. We’re comparing cells to cells, not ICE to BEV.

                    If it contains energy, there’s probably a way to make that energy release in an uncontrolled fashion. As energy densities increase, so does the risk if that happens.

                    Luckily batteries are built such that it’s actually quite hard to ignite them. As are fuel tanks for the same reason.

                    Cool. That’s not the only combustible material in a cell. And since a solid state battery only changes the electrolyte, everything else is unchanged. Meaning they are not significantly safer, because several types of liquid electrolyte aren’t flammable. Crucially, this is also a reason why solid state batteries are pointless for the foreseeable future, and only bring negatives to the table.
