Dangers of LI-ion batteries

There have been a few such cases already, but for occupants it's not much worse than leaking petrol catching fire after a crash. The main difference is that it requires a large quantity of water to extinguish (actually to cool the cells surrounding ones that are already alight to prevent them catching fire before the burning ones have burnt out), whereas petrol fires can be put out more easily using firefighting foams. The burning cells also tend to launch themselves like rockets out from the vehicle, which could injure bystanders/firemen or start other fires nearby.

Samsung survived their burning phone problems a few years ago. As long as the trend for things like extremely thin smart phones continues, there will always be a call for packing as much power as possible into a very small space, and that need for increased energy desnity leads businesses and consumers to accept these more volatile battery chemistries.
