With solid state batteries you can puncture them, cut them, and shoot them with a bullet. It's much harder to make them catch fire and they keep working: https

Same as LFP batteries then?

  No.

    Sure LFP won't keep working after being shot, but is that a difference that matters? The important part is the "doesn't catch fire".

      LFP batteries do catch fire. They just don't burn as vigorously as NCM batteries.

        Solid-state batteries don't completely eliminate fires. When short circuited they heat up drastically, starting and enhancing fires.

        Small lab scale test and having 100kg of high density batteries in a box aren't the same thing.

Again, 'solid state' is a marketing term. There are lots and lots of different things that exist under the larger term 'solid state'. And they have different properties. And in traditional liquid batteries there are also a number of changes happening that change the behavior of the battery under these conditions. Making judgment on that stuff based on small scale lab test just doesn't really hold up. These batteries all have to go threw automotive testing. And by the time they are actually commercial, then you can compare them to the newest generation of liquid batteries. And then maybe the perform slightly better or maybe not.

No. It's a battery with a solid electrolyte: https://en.wikipedia.org/wiki/Solid-state_battery https://en.wikipedia.org/wiki/Solid-state_battery https://en.wikipedia.org/wiki/Solid-state_electrolyte https://en.wikipedia.org/wiki/Solid-state_electrolyte They've been around for a long time.
