    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.

        So you’re more than a decade behind on LiB tech. Got it. Now it makes sense why you think this boondoggle is even worth discussing.

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

        As in solid state has lower range, lower cycle life, and higher cost. Quite an amazing hill to be attempting to defend. lmfao
