            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.

                    They are significantly safer. Current li-ion in cars have some very bad failure modes; just puncturing them can release a massive, uncontrollable fire that could potentially keep itself going while fully submerged in water. Now, even those are somewhat overblown–they’re pretty well protected in cars–but these problems aren’t universal to all lithium chemistries, much less all batteries in general.

                    Yes, they can catch fire. No, you don’t need four fire trucks worth of water tanks to put them out. This matters.

                    Other than the massive difference in mileage and reduction in charge time? Sure

                    Why do you think there are so many manufacturers trying to scale solid state? For fun?
