A good design would allow for the energy of a single cell failure to be dissipated in a way that doesn't run away. If it doesn't achieve that, it's a bad design.

This is the prime issue about cell power density: massive energy transfer across low impedance makes things hot enough that the housing will not stop heat transfer into a very volatile compound.
I agree that if they used non flammable organic compounds there's less fire, but I'm not so sure the solid state batteries won't cause fires either.
