However much safer electric cars might be than their gas counterparts, they can still catch fire -- and BYD wants to reduce the chances of that happening. It will soon roll out a Blade Battery that's meant to be safer without compromising performance. Its high temperature for exothermic reactions, low (and slow) heat release and lack of oxygen release combine to form an energy pack that shouldn't "easily" catch fire. A nail puncture test didn't even significantly raise the temperature of the battery (it didn't venture above 140F), let alone set it ablaze. It also avoided fires due to bending, crushing, overcharging and overheating.
