Electric cars, have same issues with Lithium batteries..Imagine u buy one because you think u are saving the planet,because you are ignorant to the strip mining involved around the world, involving a lot of child labor, the fact China processes 80% of Lithium on the planet, their factories emit highest levels of CO2 on the planet. Then the battery, which put tons of CO2 into the atmosphere, just to strip mine the materials, ship around the globe for processing assembly, then shipped around the world to be put into an EV, the battery burst into a white hot fire as you and your family sleeps, never to wake again. But,hey,you were just trying to save the planet
