Battery manufacturing is hard. Everyone was really impressed by that "record-breaking" installation Tesla made in South Australia, but that 100 MWh installation is really less than 2000 cars, and Tesla needs to build five times that much per month to keep up with demand. I think people focus on lithium because it's in the name, but lithium access is nowhere near the hardest problem facing battery manufacturers (and correspondingly it's a small percentage of the cost).
