Lithium is the 25th most common element in the earth's crust, but because it is so reactive it is never found in its free state, but it is found everywhere.
Extracting it is energy demanding and vast amounts of electricity are needed, so recycling batteries may be soon be economically viable.
I agree with Milligoon: scientist often disagree, but sadly much research is externally funded by organisations with a vested interest, and it always is prudent not to upset the people controlling the money. So dissenting voices often don't get muck exposure...
