Default Electric vehicles production limted by REEs and Li

"The numbers show that the production of lithium-ion battery packs for vehicle propulsion is and will always be limited by the rate of production for lithium, because even if all of the minable lithium deposits were exhausted only enough lithium would be produced to build 450,000,000 vehicles per year at equilibrium between mining and recycling at a 100% recovery rate. Today’s fleet of cars is already at 750,000,000 globally with nearly half in North America and 90% or more in North America, Europe and Japan.

I have written elsewhere about how the maximum production of rare earths required to get lanthanum and neodymium to build nickel metal hydride batteries and electric motors and permanent magnet generators is limited, and at this time, is confined almost entirely within China.

It cannot be overlooked that the electric motors in many electrified vehicles intended to utilize permanent magnet-type electric drive motors depend for their maximum efficiency on neodymium-iron-boron magnets, so that even electrified vehicles using lithium-ion batteries will have their total production limited by the availability of rare earths.

The numbers show that for the next generation, at least 25 years away, the total annual possible production of electrified personal vehicles will be limited by the rate of natural resource production, particularly of the rare earths and lithium." Jack Lifton
