Lithium prices have been doubling almost every 4 years since lithium mining can't keep up with existing demand. The more people go EV the pricier lithium will become as there is not enough to keep up with current demands. And if you really want to be held hostage, extremely rare Earth minerals like Neodymium which are needed by EV vehicles are so rare that you can expect prices to climb to the cost of gold or platinum if they dare to increase productions from current levels. In other words, it's game over for the EV market unless they find new sources to power the cars in the future.
