I would disagree with the suggestion that there is no correlation between battery energy density how violently they burn. There is a direct connection between the state of charge and how aggressive the failure is for lithium batteries in cases where they are punctured, cut, or folded. (Not uncommon in car crashes)

As a source of ignition(and initial explosion), sure, the charge matters. That doesn't mean that more charge makes it more likely to ignite, regardless of other factors. The construction of the battery itself is much more important there, and when we're talking about comparing solid state batteries(which is what this is about) and lithium ion solution, that's a big difference. It's the material that burns, not the charge.
