The lithium batteries are not more flammable than other batteries because of the lithium, but because most of them use organic electrolytes instead of water-based electrolytes. A discharged sodium or lithium battery does not have metallic sodium or lithium. Fully charged sodium or lithium batteries contain the sodium or lithium as metals, which would react in a similar way with air or water, if the battery would be cut to expose them to the environment.
