The article is about what raw materials may be in short supply as the world transitions to electric vehicles. Lithium-based batteries are expected to remain dominant as they are very efficient and so much know-how exist about them. The world is not expected to run out of lithium as existing reserves will cover the demand for many decades to come. Also, the reserves are likely to expand to meet demand. Especially if the cost of lithium increases. Cobalt, apparently, is the real bottleneck and most of it is mined in the Democratic Republic of Congo under unsafe working conditions. Fortunately, researchers have invented alternative lithium battery chemistries that doesn't require cobalt but are still as efficient as them. Batteries without nickel is also being researched but those are further in the future. Recycling is still more expensive than mining raw materials. Making recycling cheaper would make the shortage problem easier to manage.
