That's not a battery, that's a reusable bomb. Good thing they also figured out how to keep them from having runaway reactions. | ||

It's just a 92kWh battery. There are many cars with 100kWh or more on the market already. And that's only a fraction of the energy stored in an average gas tank (upwards of 500kWh). A combustion car just loses most of that energy to heat from actual explosions. From a physics perspective, a normal car is a much bigger bomb than even the longest range EV. | ||

Batteries are much less powerful bombs than fuel tanks, because they cannot produce a so great volume of gas. Batteries are dangerous mainly as sources of fire that is difficult to extinguish. For instance extinguishing with water may actually cause an explosion, by gas produced by the decomposition of water. Most lithium-based batteries are more dangerous than other batteries not because they are batteries, but because they use an organic electrolyte instead of a water-based electrolyte. So their electrolyte is a fuel, which may explode when the battery catches fire. However, there is much less electrolyte in a battery than fuel in a fuel tank, so the volume of expanding gas during an explosion is much less. | ||
