Those who hype the "green" ecological benefits of battery powered electric cars never seem to account for the impact of manufacturing the batteries and caustic battery acid or their ultimate disposal and/or recycling.
What disposal or recycling systems are in place to accommodate the tremendous amount of burned out batteries a big move to electric cars would generate? How much of the acid will just be poured into the ground at the local junkyards?
In 20 years will we have another pollution/health crisis resulting from the manufacture and handling of the batteries and acid?
Most electric car batteries don't use lead and acid. They use lithium and an alkali electrolyte.
So, yeah, what are you going to do with all that lithium? Have to recycle it, I guess. It's valuable.
And lithium, like hydrogen (same column of periodic table) required lots of energy to liberate. Where does this energy come from? Natural gas, coal, and nuclear electricity.
