I think for 90% of the car it's the same mix of steel, aluminium, copper, rubber, urethane, vinyl and so forth as for any other car.
While this is true, lithium Ion batteries contain hardly any actual lithium. They are mostly nickel, copper, aluminium and carbon by weight with a weird organic solvent electrolyte. The lithium is present dissolved in the electrolyte and the physical quantities are pretty small. Cobalt and nickel would be the potentially investable components.
Specialized materials in EVs are mostly in motors -- any permanent magnet motor is going to be using rare earth magnets, so neodymium, cerium, samarium. The main producers are in China.
