At the present rate of production, Lithium will last for 400 years. That's just the known reserves- there would be more discoveries every year as mining technologies improve. Even if you increase the product 10 times (unlikely), you get at least 40 years of Lithium with the known reserves. So, Li is not going to be a problem for electric vehicles in the short term. In the long term, you will have Sodium Ion batteries which are currently used for power storage in microgrids.

The point the story makes is that if Europe, China and India (and companies) stick to their plans, the production rate will increase massively, and replacing even half of the vehicles with EVs would see rapid depletion. And rapid increase in the cost of batteries as demand rises. (Not talking about accuracy of info in the story, no clue about that.)
