As outlined below, lithium, used in the batteries of the sacred electric cars is a wee bit dangerous, or potentially so: “lithium-ion batteries have a volatile, flammable electrolyte. So, while there are safeguards to avoid fires, all the combustible ingredients are still there. Flames can accelerate through chain reactions, known as thermal runaway. Big batteries are made up of several cells packed together. Current is constantly flowing inside, which generates heat. If there are no barriers between the components, a failure in one part quickly cascades through. While elaborate (and critical) equipment for cooling the system is put in place, it draws on the energy of the actual powerpack and reduces its output. In addition, when charged, a coat of lithium metal can form on the surface and dendrites, or needle-like structures can grow, and lead to short-circuits.”
