I can't seem to find the one I had encountered (I believe on the MyNissanLeaf forum) that concluded that the battery resources couldn't even address all of the U.K.'s driving consumption. I do still see this one, though it doesn't go so far as to say it can't be done but does focus on the constrained resources and therefore the importance of getting the most mile conversion per battery capacity:

The point is quite valid that there are major constraints in battery supply. I would love to see studies indicating that we had plenty of good batteries available and can can all switch to EV driving today. We can't simply flip a switch and replace all vehicles with EVs. Until (if ever) we have that type of supply, being efficient in our allocation of these scarce resources is a worthwhile tactic.
An important factor in the study:
"The calculations did not take into account the upstream CO2 in fuel extraction, refining and transportation
". Kind of an important piece of the big picture isn't it?
The "study" also assumes a constrained battery supply - with no mention of limited resources being the cause.
No one is suggesting that one morning all ICE vehicles will be gone and be replaced by EV's, nor that battery production could handle an instantaneous switch.
Still interested in any source suggesting that raw materials are too scarce to supply enough batteries. It does indeed take time to build factories to produce batteries, and those factories indeed do not exist today. But to extrapolate from that that they never can/will exist is pure nonsense.
