I would disagree about lithium ion batteries being more dangerous - gasoline is far more energy dense for one. A slower release is actually a good thing for safety compared to the alternative, a very fast intense one. Besides, just a single mode of failure is not an apt comparison. - You cannot create a fuel air bomb by throwing lithium ion batteries into your basement and igniting it when the concentration is correct. - You cannot suffer carbon monoxide poisoning from lithium ion batteries.
