About 15 million metric tons. That is about 2 kg per person today. [1]
Given under 1 gram of lithium per cell, that is 2000 batteries per person. [2]
That is 2000*10Whrs=20kWhrs per person. That appears to be plenty for now.
But lithium extraction is shitty for people and environment. See Nature paper: [3]. Conclusion: Not easy to recycle, and recycling may end up using more greenhouse gas than new extraction.
Let's get into hydrogen, now.
