Hmm. "Although the emission of toxic gases can be a larger threat than the heat, the knowledge of such emissions is limited." from a study titled "Toxic fluoride gas emissions from lithium-ion battery fires"
CDC has some information about HF gas but they don't tend to link it to battery fires. Not sure about any of the amounts but it's just not something you want to burn in a firepit I suppose.
