That’s technically true but also true for a very wasteful combustion reaction with all the energy gasoline has in it. It’s not quite that simple, as the potential energy for, say, lithium oxidation is much higher than you’d get from charging and discharging a battery.
The energy stored is only part of the equation.

I am not saying this as a dig on EVs, ICE vehicles can go die in a hole for all I care, its just a reality that more energy is more energy and you can’t escape it.

I understand that. My point was that the lithium oxidation from combustion vastly outstrips the power charged. You could create a hell of a fire with an uncharged lithium battery. The underlying reactivity of materials do not have a direct link to the battery’s storage.

I would disagree. There is a direct connection between the state of charge and how violent the failure is for the lithium battery in cases where it is punctured, cut, or folded. (Not uncommon in car crashes)

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